Pocket-sized. Sees a kilometre in darkness.
At 300 g and 144 mm long, the Alaris XQ30 is the thermal monocular that’s always in your pocket – and always ready. Detect animals at 1,050 m through total darkness, fog, and dense scrub without carrying extra kit.
Pocket thermal. The one you actually carry, because you hardly know it’s there.
Detect what your eyes cannot – in any conditions.
The 384×288 uncooled sensor with 17 μm pixel pitch and system NETD below 20 mK picks out warm animals against cold backgrounds in dense bush, open paddock, fog, and smoke. Nine selectable colour palettes – including White Hot, Black Hot, and Red Hot – let you tune the display to conditions.
System NETD in millikelvin. Detects the faintest heat signatures, even in low-contrast environments where conventional night vision fails.
Wide scan to close detail. 2–8×.
The F30/1.2 objective and 13.3° field of view let you sweep paddock edges at 2× and zoom to 8× to confirm a species in seconds. Smooth digital zoom with no pause or button hunting.
Frost-resistant. Vivid at any temperature.
The frost-resistant AMOLED display at 640×400 pixels stays sharp and vivid from midsummer heat to winter pre-dawn cold. What the sensor captures, the screen renders faithfully.
Stream live to your phone.
Built-in dual-band Wi-Fi (2.4 / 5 GHz) connects to the Pulsar Wild Vision app for live streaming to a smartphone, remote control, and over-the-air firmware updates – all without cables.
16 GB onboard storage
Capture photos in JPG and video in MP4 directly to 16 GB of internal memory. Charge via USB-C while recording in the field.
IPX7 waterproof, magnesium alloy body
Rated IPX7 for full waterproofing. The rugged magnesium alloy housing resists drops and dissipates heat, staying reliable from −20°C to +40°C.
Always with you. On-target the moment it leaves your pocket.
At 144×41×69 mm and just 0.3 kg with battery installed, the Alaris XQ30 disappears into a jacket pocket. The symmetrical form and intuitively placed buttons mean you are scanning the moment you raise it, whether that’s at dawn, dusk, or 2 am in the field.
Find warm bodies. Even in total darkness.
The 13.3° field of view sweeps tree lines, paddock edges, and wetland margins fast. Animals hidden in darkness, dense scrub, or heavy morning fog appear immediately as bright heat signatures – even before your eyes have adjusted to the dark.
Run all night without stopping. Swap in seconds if you do.
The removable APS 3 lithium-ion battery (3,200 mAh) delivers 7.5 hours of continuous use at 22°C. When it runs low, swap in a spare in seconds, no tools required. USB-C charging means one cable for everything you carry.
Night vision stops here. Thermal doesn’t.
Rain, fog, smoke, and total darkness defeat conventional night vision – not thermal. The 50 Hz frame rate delivers smooth, real-time video with every warm body rendered clearly, whatever conditions the Australian night throws at you.
Compact. Capable. Ready for the field. Nothing is there for show.
384×288 uncooled thermal sensor with 17 μm pixel pitch and system NETD below 20 mK
1,050 m detection range for spotting large animals across open ground
50 Hz frame rate for smooth, real-time thermal video at any zoom level

See what others cannot. At distances that leave wildlife undisturbed.
The Lumion XL50 brings a 1024×768 HD thermal sensor, F/1.0 germanium lens and 2,300 m detection range to serious birdwatchers, wildlife researchers and conservation professionals. Identify species in total darkness, through foliage, across open water – without ever getting close enough to influence behaviour.
Authorised Australian distribution. Full local warranty support from Bintel, Sydney.
The detail to identify. The range to stay back. The Lumion XL50 is the thermal monocular serious wildlife observers have been waiting for.
The bird in the hedgerow. Clearly resolved.
Image Boost applies advanced algorithmic processing to the raw sensor output, pulling fine detail from scenes where standard thermals deliver flat, ambiguous blobs. A wader at the water’s edge, a raptor perched in dense canopy, a mammal at the treeline – each becomes sharply defined.
Sensor sensitivity, brightness and contrast are all adjustable on the fly, so you tune the image to the species and the scene rather than accepting a generic preset.
Every detail considered, for observers who never switch off.
The XL50 is built for marathon sessions – from predawn roost counts to late-night mammal surveys. Ergonomics, weather resistance and intuitive controls combine so that the tool never becomes the obstacle.
Lock on before it moves
Zoom and focus rings follow the same layout as a professional camera lens. The moment you lift the XL50, the controls are where you expect them – so you frame, focus and confirm identity before a fast-moving subject disappears.
Confident in your grip, whatever the conditions
Wear-resistant rubber armour wraps the chassis for a secure hold in rain, mud or cold. It absorbs knocks, repels dust and moisture, and wipes clean at the end of a long session in the field.
Rated for the conditions you actually work in
IPX7 waterproofing and an operating range of −25 to +40°C cover everything from an alpine winter survey to a tropical coastal count. The chassis is built to perform, not to be babied.
Set it up the way you work
A symmetrical layout, adaptable hand straps and programmable buttons suit left and right-handed observers, and a personal user mode stores the settings you reach for most.
Grab it and go – wherever the survey takes you
The included case is built to work, not just store. Modular straps integrate with your backpack or field harness for a genuine 3-point carry, so the XL50 is always within reach and never in the way.
Sharp from the first light, even in a frost
The frost-resistant AMOLED HD display delivers a crisp, true-to-sensor image regardless of temperature. On cold mornings when conventional optics fog and digital screens dim, the XL50 shows you everything.
All night. With a spare in your pocket if you need it.
The APS 3 Li-ion pack delivers around 7 hours at +22°C. When a survey runs long, swap in a fresh pack in seconds – no cables, no waiting, no missed sightings.
Recharge over USB Type-C with Power Delivery support for a faster top-up, or drop the removed pack onto any Qi wireless pad when you are back at base.
2,300 m of reach. Every pixel working for you.
A 14° field of view sweeps habitat fast. An F/1.0 lens draws in thermal detail at the far edge of detection range. The result is an instrument that keeps up with wildlife – and with observers who know what they are looking for.
Everything you need in the field. Nothing you have to add.
Detail at the limits of detection
An F/1.0 objective gathers maximum thermal energy, so fine detail holds up in cool ambient conditions and at the outer edge of the 2,300 m detection range – where lesser lenses give you noise.
Document what you see, without slowing down
Record video and stills directly to 64 GB of built-in memory as .mp4 and .jpg files. No SD card to lose in the dark, no phone to pair before you can capture.
Share the sighting in real time
Dual-band 2.4 / 5 GHz Wi-Fi pairs with the Wild Vision app for live streaming to a phone or tablet, instant sharing with a team, or full remote control when the XL50 is deployed on a mount.
Colour palettes
Choose from nine thermal colour palettes to match the scene, the species and your own preference.
Everything that matters. In a single instrument.
HD 1024×768 thermal sensor with sub-20 mK system NETD
2,300 m detection range for confident long-range observation
Wide 14° field of view for fast target acquisition

Detect. Range. Identify. All from one device.
The Orni XG35 integrates 1,800 m thermal detection, a 1,500 m laser rangefinder, and electronic image stabilisation into a single monocular that runs for 12 hours. Built for birdwatchers and wildlife observers who push deep into the field.
Twelve hours of thermal. Stabilised views, integrated ranging, and the battery to use them all night.
Faint signatures. Long distances. Sharp results.
The 640×480 uncooled European sensor with 12 μm pixel pitch and system NETD below 20 mK resolves subtle heat differences at 1,800 m – through rain, fog, and dense scrub. Nine colour palettes let you tune contrast for the conditions at hand.
Kilometres of detection range in total darkness. No ambient light needed, no torch, no compromise to your night vision.
Range to 1,500 m, ±1 m
The Class 1 eye-safe laser rangefinder gives precise distance readouts up to 1,500 m in complete darkness. Switch between metres and yards on the fly.
Tripod-free clarity at 20×.
Electronic image stabilisation corrects hand shake across the full 2.5–20× zoom range. Hold a steady image on a perched raptor or a mammal at 1,500 m without reaching for a tripod.
Crisp 1024×768. Auto-brightness.
The frost-resistant AMOLED HD display at 1024×768 adjusts brightness automatically – readable at midnight, usable at dawn. What the sensor resolves, the display renders faithfully.
12 hours, quick-swap APS 5
A removable APS 5 (4,900 mAh) plus a 3,200 mAh built-in battery together deliver 12 hours. Swap the external pack in seconds without interrupting a session. Universal USB-C charging works with any power bank.
Ambidextrous, one-handed operation
Ergonomic grip works equally in left or right hand. Six conveniently placed buttons, haptic feedback for glove use, and a belt clip plus hand strap included. Optimised for long observation sessions in the field.
Identify species at range. Species-level detail without disturbing behaviour.
The 12.5° field of view sweeps treetops, paddock edges, and wetland margins efficiently. Zoom to 20× and the integrated rangefinder tells you exactly how far away that subject is. Built for the Australian birdwatcher who goes out before dawn and stays out after dark.
See through the dark. Find what hides.
The Orni XG35 resolves heat signatures at distances where conventional optics go blind – nocturnal animals, dense vegetation, fog, and rain are no longer obstacles. At 1,800 m, you are the apex observer.
12 hours. No recharge required mid-session.
The dual battery system pairs a quick-swap external APS 5 pack (4,900 mAh) with a 3,200 mAh built-in cell. When the external pack depletes, the device keeps running on the internal reserve while you swap. USB-C Power Delivery supports 5 V and 9 V fast charging.
IP67. Magnesium alloy. Ready for anything.
Full IP67 dust and waterproof protection paired with a magnesium alloy chassis handles the Australian bush, wet scrub, and desert heat alike – operating from −25°C to +40°C. It is built for observation, not for the shelf.
Range, detect, stabilise, record. All night, every night.
640×480 European uncooled thermal sensor, 12 μm pixel pitch, system NETD below 20 mK
1,800 m detection range for spotting wildlife and birds at extended range

$8,399.00
Thermal binoculars. HD clarity, 2,300 m range.
The Ventex XT50 delivers Europe’s highest-resolution thermal binocular experience – a 1280×1024 sensor, 17.5° wide field of view, and dual-eye observation that keeps you scanning longer without fatigue.
Wide-binocular vision. A 17.5° field and European HD sensor that reveals every corner of the landscape at once.
Pulsar’s sharpest thermal sensor. In a binocular.
A 1280×1024 uncooled European sensor with 12 μm pixel pitch and system NETD below 20 mK renders subtle heat differences with extraordinary fidelity. Paired with the HD AMOLED 1280×960 microdisplay, every feather, fur edge, and distant body reads with defining clarity.
Kilometres of detection range. Spot distant animals, birds at flight altitude, and hidden subjects in conditions where conventional optics see nothing.
17.5° – the widest thermal binocular view.
At 17.5° horizontal (30.7 m at 100 m) and a 62–74 mm interpupillary range, the Ventex XT50 fills both eyes with terrain. Less panning, more finding. Survey wetlands, open plains, and forest canopies the way you experience them in daylight.
1,500 m ranging. ±1 m accuracy.
The built-in Class 1 eye-safe laser rangefinder reads distance to 1,500 m with ±1 m precision, in complete darkness, without disturbing your subject. Switch metres and yards on the fly. No separate device to carry or fumble for.
2–16× zoom. Detail at every level.
A 1280×1024 sensor behind 2–16× digital zoom means maximum magnification doesn’t mean maximum pixellation. Distant birds and animals retain identifying detail at full zoom, day surveys or overnight.
8 hours. Hot-swap capable.
A B-Pack Mini external cell (3,200 mAh) plus a 4,000 mAh internal battery deliver 8 hours of operation. When the external pack depletes, the device switches to the internal reserve while you swap. USB-C Power Delivery charges at 5 V and 9 V.
Magnesium alloy. IPX7. −25°C to +50°C.
A one-piece magnesium alloy chassis handles the weight of full binocular optics without flex. IPX7 waterproofing protects in driving rain and splashes. Operating range from −25°C to +50°C covers every Australian season.
Both eyes working. Hours without discomfort.
Thermal monoculars tire the dominant eye – the Ventex XT50 does not. Natural dual-eye observation distributes the load, so pre-dawn surveys stretch into mid-morning without strain. The 62–74 mm interpupillary adjustment and 15 mm eye relief accommodate the full range of observers.
You see them. They don’t see you.
The 1280×1024 European sensor detects heat at up to 2,300 m – revealing birds in flight, animals at scrub edges, and wildlife on distant ridgelines long before they sense your presence. No light, no noise, no disturbance.
Less sweeping. More observing.
A 17.5° horizontal field (30.7 m at 100 m) lets you read an entire wetland edge or track a moving flock without constant panning. Birdwatchers, naturalists, and wildlife carers all benefit from a view wide enough to hold multiple subjects simultaneously.
Dusk to dawn. Hot-swap ready.
The dual battery system – a 4,000 mAh internal cell plus a hot-swappable B-Pack Mini – keeps the Ventex XT50 running for eight hours straight. Swap the external pack mid-session without powering off. USB-C Power Delivery charges fast enough to be ready for the next night out.
Every capability, purpose-built. Night after night.

The QHY5III462 camera uses the Sixth Generation Sony 2.1 megapixel IMX462 STARVIS CMOS sensor. The pixel size is 2.9um making it the same size and resolution as the sensor used in the QHY5III290 camera that has been so successfully used for planetary imaging by some of the best planetary imagers in the world. Like other cameras in the 5III series, the QHY5III462 is USB 3.0 powered and controlled. No additional power is required.
The IMX462 sensor is back-illuminated and incorporates new technology that gives it some significant advantage over other planetary cameras: First, the IMX462 sensor has sHCG (Super High Conversion Gain) for very low read noise at high gain. This is ideal for stacking hundreds or thousands of short planetary images. Second, it is exceptionally sensitive in the NIR.
In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous Sony BSI sensors, allowing photons of longer wavelength to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near infrared (NIR) light. The RGB filters over the pixels become transparent at NIR wavelengths, so the sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.
The peak QE in the NIR around 800nm is as high as the peak QE in the visible wavelengths. For planetary imagers using a methane filter that passes light around 880nm this is welcome news.
BSI
One benefit of the back-illuminated CMOS structure is improved sensitivity. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.
In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.
Extended Near Infrared Sensitivity
Logically, one would think, each generation of Exmor sensor would be built upon and incorporate all of the improvements of the generation immediately preceding. However, this was not the case with the fifth generation Exmor R sensors.
The first back-illuminated sensors used shallower pixel wells (like the third-generation front- illuminated designs) than the physically deeper pixels of the fourth generation. So, while the back- illuminated structure increased the sensitivity in the visible range by 2X, the shallower pixels did not improve the NIR. The answer to this is seen in the latest, sixth generation, Sony Exmor R sensors, like the IMX462. Using physically deeper pixels in conjunction with the back-illuminated structure has dramatically improved the sensor’s sensitivity to both the visible and near infrared wavelengths.
sHCG Mode
Another advantage of the QHY5III462 is the camera’s “Super High Conversion Gain” capability. By using a lower capacitance, a small amount of charge can be converted to a high voltage resulting in higher sensitivity in low-light conditions. The readout noise of the QHY5III462 in high gain mode is as low as 0.5 electrons!
The test exposures below demonstrate the low light improvement over the IMX290 sensor. The QHY5III462C image is on the left and the corresponding QHY5III290C image is on the right. The low light conditions and exposures are identical for each top and bottom pair of images and a UV/IR filter was in place for each camera. So this test demonstrates the QHY5III462C’s increase in sensitivity and SNR over the QHY5III290C under the same conditions in the visual light spectrum alone.
Color and Mono Imaging
The filter matrix in the IMX462 uses organic dye filters. These filters are very efficient at visible wavelengths but become completely transparent in the NIR. For this reason, good RGB color balance requires an external UV/IR filter that blocks NIR wavelengths.
Many color cameras build this UV/IR filter into the camera or optical window for normal color imaging. However, in order to fully exploit the capabilities of the 462C sensor, in the QHY5III462C camera the optical window is AR coated only with no UV or IR blocking. Instead, the QHY5III462C camera includes two 1.25″ screw-in filters, a UV/IR cut filter to isolate the visible wavelengths for normal RGB imaging and an IR850 filter that will cut the visible wavelengths but pass wavelengths above 850nm.

At just over 4 inches in diameter and a few inches thick (IMX585), the new miniCAM8 is a compact, high-resolution, high-performance, cooled imaging system capable of exceptional, high-quality deep space images as well as high-quality, high-resolution planetary images.
So often, compactness in astroimaging is achieved at the expense of some other critical feature found in multi-component cooled systems, such as sensor quality or thermoelectric cooling, etc. Such is not the case with the new miniCAM8. Based on Sony’s IMX585 8 MP sensor, the miniCAM8 includes full TE cooling capable of reaching a delta of -45℃ from ambient along with a built-in 8-position filter wheel for complete LRGB and narrowband imaging.

The PoleMaster is an easy, convenient and fast way to achieve excellent polar alignment. It has been recognized by astronomy enthusiasts around the world and has become a must-have for anyone using an equatorial mount for visual use or for imaging. The PoleMaster electronic polar axis alignment device is a patented product of QHYCCD and is protected by Chinese, US patents and International PCT.
As any seasoned astronomer would agree, achieving good polar alignment is not an easy task. You may spend hours under precious dark sky trying to get that perfect polar alignment, but in the end you may not know whether good alignment has in fact been achieved. Even after you have obtained good alignment, a gentle knock on the mount may send the polar alignment off and you may have no other choice but to start from scratch again. With an hour here and an hour there trying to get polar aligned, it soon will be dawn and time to pack up the gear.
The PoleMaster is a great solution to this problem. The PoleMaster is an innovative product pioneered by QHYCCD to relieve the pain of polar alignment. Using PoleMaster and following a few simple, easy-to-follow, steps you can achieve perfect polar alignment in 2-3 minutes, with an accuracy of up to 30 arc seconds.
With PoleMaster, You don’t need to rotate the telescope to some uncomfortable position to keep the optical polar axis of the equatorial mount unobstructed. Also, you don’t need to squat down to look through the polar axis scope. You don’t need to turn off all the light sources to allow the naked eye to adapt to the darkness and look for the Polaris in the field of view. You also don’t need to enter the date and time and then rotate the equatorial mount to a strange angle, finally you don’t need to adjust the equatorial level. With the PoleMaster you can observe the alignment of the polar axis at any time, as well as continuously monitor the polar axis. When the equatorial mount moves inadvertently, you can also tune it back without having to redo everything.
The PoleMaster’s pixel resolution is approximately 30 arc seconds. The camera’s pixel matrix itself is a good ruler, so the accuracy it measures is much higher than the accuracy of the macroscopic lens. In the best case it can achieve an alignment accuracy of 30 arc seconds.
Wide Field of View: The electronic polar mirror has a large field of view of 11 degrees x 8 degrees, so it is easy to find the Polaris.
Once you have calibrated with a PoleMaster, you only need to perform a single-star sync (one-star calibration). This greatly facilitates the setup of an equatorial mount.
With a suitable adapter ring, the PoleMaster can be mounted to any equatorial mount. Even single-axis equatorial mounts that have no ability to correct in declination will benefit because with the PoleMaster, after the polar axis is aligned, the amount of drift in the declination direction will be very small, which can further improve the performance of such an equatorial mount.

QHY268M/C 是新一代背照式 CMOS 相机,具有真正的 16 位 A/D 和 3.76um 像素。这款索尼新传感器是一款理想的 CMOS 传感器,不会出现放大器辉光。16 位 A/D 可对整个满阱范围进行高分辨率采样。数字化 0-65535 级别可产生具有连续灰度等级的平滑图像。QHY268M/C 是一款基于索尼 IMX571 传感器的冷却背照式 CMOS 相机,具有原生 16 位 A/D 和 3.76um 像素。
1GB DDR3 图像缓冲区
为了保证整个26MP传感器的高速不间断的数据传输,QHY268配备了1GB DDR3图像缓冲区。最新一代CMOS传感器的像素数非常高,对临时和永久存储的内存要求也更大。QHY268采用了高达1GB的大容量内存,数据吞吐量翻倍。这种超大的图像缓冲区满足了新一代CMOS高速图像采集和传输的需求,使得多帧拍摄更加流畅,卡顿更少,进一步减轻了电脑CPU的压力。
QHY268M 有一个独特的内部湿度传感器(而 QHY268C 没有)。下图中的蓝色曲线表示湿度。
多种读出模式是QHY 16位相机(QHY600/268/461/411)独有的,不同的读出模式驱动时序等不同,导致性能不同,详见“多种读出模式及曲线”部分。
在一些背照式CMOS相机中,你可能会发现某些类型的热噪声会随时间而变化。这种热噪声具有典型热噪声固定位置的特点,但其大小与曝光时间无关,而是每一帧都呈现出自己的特点。QHY600/268/461/411采用了创新的抑制技术,可以显著降低此类噪声的表观水平。
UVLO(欠压锁定)是为了保护电子设备免受异常低电压造成的损坏。
日常生活经验告诉我们,电器的实际工作电压不能明显超过额定电压,否则会损坏。对于相机这种精密设备,长期在过低的输入电压下工作也会对相机的工作寿命不利,甚至会使电源管理器等器件因长期过载而烧毁。在2021.10.23稳定版之后的一体机驱动和SDK中,当相机输入电压低于11V时,相机会发出警告。
CMOS 传感器包含一些水平条带是常见现象。通常,随机水平条带可以通过多帧堆叠去除,因此不会影响最终图像。但是,周期性水平条带无法通过堆叠去除,因此可能会出现在最终图像中。通过在单帧模式或实时帧模式下调整 USB 流量,您可以调整 CMOS 传感器驱动程序的频率,并且可以优化图像上出现的水平条带。这种优化对于在某些情况下去除周期性条带非常有效。
特定 USB_TRAFFIC 值下的典型周期性水平噪声。
关闭并重新打开电源,重新启动相机
相机设计为使用 +12V 重新启动相机,而无需断开和重新连接 USB 接口。这意味着您只需关闭 +12V 然后重新打开电源即可重新启动相机。此功能对于在天文台远程控制相机非常方便。您可以使用远程控制电源重新启动相机。在远程控制的情况下,无需考虑如何重新连接 USB。

QHY294 Pro 是一款 4/3 英寸背照式相机,配备索尼 IMX294(彩色)和 IMX 492(黑白)传感器。294 Pro 拥有 1170 万像素,4.63um,14 位 A/D。IMX294 和 IMX492 芯片拥有 4680 万个 2.315um 像素,索尼将其在芯片上 2×2 合并,以创建传感器所宣称的 1170 万个 4.63um 像素阵列。QHY294 Pro 系列相机能够锁定和解锁片上合并,以提供两种读出模式。第一种模式读取传感器“锁定”模式,产生 1160 万像素,像素大小为 4.63um,每像素 14 位。第二种读取模式解锁合并,产生 4680 万像素,像素大小为 2.315um,每像素 12 位。
QHY294 Pro CMOS传感器具有双增益模式,HGC(高增益)和LGC(低增益)。当增益设置为1600时,QHY294 Pro会自动切换两种模式,您将获得HGC模式的超低读取噪声(1e-至1.6e-)和在切换点设置下约14.5ke-的满阱容量的好处。
背照式 CMOS 结构的一个优点是提高了满阱容量。在典型的前照式传感器中,来自目标进入传感器感光层的光子必须首先穿过嵌入在感光层正上方的金属布线。布线结构会反射部分光子并降低传感器的效率。
在背照式传感器中,光线可以从背面进入感光表面。在这种情况下,传感器的嵌入式布线结构位于感光层下方。因此,更多的入射光子撞击感光层,并在像素阱中产生和捕获更多的电子。光子与电子产生的比率称为量子效率。量子效率越高,传感器将光子转换为电子的效率就越高,因此传感器对捕捉暗淡物体的图像就越敏感。
在 DSLR 实现中,有一个 RAW 图像输出,但通常不是完全 RAW。仔细检查仍可见一些降噪和热像素去除的痕迹。这可能会对天文学图像产生负面影响,例如“吞星”效应。然而,QHY 相机提供真正的 RAW 图像输出,并生成仅由原始信号组成的图像,从而为采集后天文图像处理程序和其他科学成像应用保持最大的灵活性。
基于近20年的冷却相机设计经验,QHY冷却相机实现了全面的露水控制解决方案。光学窗口内置露水加热器,可防止腔体内湿气凝结。腔体窗口的电加热板可防止露水形成,传感器本身通过我们的硅胶管座设计保持干燥,以控制传感器腔内的湿度。

多种读数模式
多种读出模式是QHY 16位相机(QHY600/268/461/411)独有的,不同的读出模式驱动时序等不同,导致性能不同,详见“多种读出模式及曲线”部分。
随机变化热噪声抑制功能
在一些背照式CMOS相机中,你可能会发现某些类型的热噪声会随时间而变化。这种热噪声具有典型热噪声固定位置的特点,但其大小与曝光时间无关,而是每一帧都呈现出自己的特点。QHY600/268/461/411采用了创新的抑制技术,可以显著降低此类噪声的表观水平。
UVLO 保护
UVLO(欠压锁定)是为了保护电子设备免受异常低电压造成的损坏。
日常生活经验告诉我们,电器的实际工作电压不能明显超过额定电压,否则会损坏。对于相机这种精密设备,长期在过低的输入电压下工作也会对相机的工作寿命不利,甚至会使电源管理器等器件因长期过载而烧毁。在2021.10.23稳定版之后的一体机驱动和SDK中,当相机输入电压低于11V时,相机会发出警告。
优化 USB 流量以最大程度减少水平条带
CMOS 传感器包含一些水平条带是常见现象。通常,随机水平条带可以通过多帧堆叠去除,因此不会影响最终图像。但是,周期性水平条带无法通过堆叠去除,因此可能会出现在最终图像中。通过在单帧模式或实时帧模式下调整 USB 流量,您可以调整 CMOS 传感器驱动程序的频率,并且可以优化图像上出现的水平条带。这种优化对于在某些情况下去除周期性条带非常有效。

调整 USB 流量以避免周期性的水平噪声。
关闭并重新打开电源,重新启动相机
相机设计为使用 +12V 重新启动相机,而无需断开和重新连接 USB 接口。这意味着您只需关闭 +12V 然后重新打开电源即可重新启动相机。此功能对于在天文台远程控制相机非常方便。您可以使用远程控制电源重新启动相机。在远程控制的情况下,无需考虑如何重新连接 USB。

背照式 CMOS 结构的一个优点是提高了满阱容量。这对于像 QHY533 Colour 这样的小像素传感器尤其有用。在典型的前照式传感器中,来自目标进入传感器感光层的光子必须首先穿过嵌入在感光层正上方的金属布线。布线结构会反射部分光子并降低传感器的效率。
在背照式传感器中,光线可以从背面进入感光表面。在这种情况下,传感器的嵌入式布线结构位于感光层下方。因此,更多的入射光子撞击感光层,并在像素阱中产生和捕获更多的电子。光子与电子产生的比率称为量子效率。量子效率越高,传感器将光子转换为电子的效率就越高,因此传感器对捕捉暗淡物体的图像就越敏感。
真实原始数据
在 DSLR 实现中,有一个 RAW 图像输出,但通常不是完全 RAW。仔细检查仍可见一些降噪和热像素去除的痕迹。这可能会对天文学图像产生负面影响,例如“吞星”效应。然而,QHY 相机提供真正的 RAW 图像输出,并生成仅由原始信号组成的图像,从而为采集后天文图像处理程序和其他科学成像应用保持最大的灵活性。
基于近20年的冷却相机设计经验,QHY冷却相机实现了全面的露水控制解决方案。光学窗口内置露水加热器,可防止腔体内湿气凝结。腔体窗口的电加热板可防止露水形成,传感器本身通过我们的硅胶管座设计保持干燥,以控制传感器腔内的湿度。
除了双级TE冷却之外,QHYCCD还在硬件上实现了专有技术来控制暗电流噪声。
