ZWO IR cut filter 2 inch is suitable for colour camera with AR protect window.
The ZWO IR Cut Filter 2 inch blocks infrared light from reaching the sensor of your CCD or CMOS camera or your expensive H-alpha filter. When imaging, the addition of this simple and inexpensive accessory will result in sharper images, and when doing solar work, the IR Cut Filter will your protect H-alpha filter from the damaging effects of infrared radiation.
Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually. However, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO IR Cut filter 2 inch will do just that.
The ZWO IR Cut filter is housed in a 2″ cell, and has internal threads so that you can stack filters together. The filter comes with a protective plastic case.
Name: IR-cut filter
Size: 2″
Thickness: 5mm+2mm(Thread)
Thread: M48*0.75 male thread

ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras. The Duo-Band filter is aimed at the astronomer who may already own a One Shot Colour (OSC) camera and wants to image using narrowband techniques or emission objects without purchasing a mono camera, filter wheel and narrowband filter set.
The Duo-Band filter offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.
The dual band pass nature of the Duo-Band filter passes light at Hα (656nm) and OIII (500nm) wavelength, and can reduce the interference from natural light sources such as moonlight, or artificial light pollution such as street lighting.
It can help improve the contrast and visibility of deep sky objects such as emission nebula using a OSC (One Shot Colour) camera.
If you are looking for a solution to deep sky photography in light pollution area, then ZWO Duo-Band Filter will be a great choice.
The Duo-Band filter can be used with all ASI cameras and EFW Electronic Filter Wheel and comes in 1.25” and 2” sizes.
Precision CNC machined from Aircraft grade alloys,hard anodised finished Cell with Laser engravings, finely polished optical surface to ensure 1/4 wavefront and <30 arc seconds parallelism over the both surfaces. Precise double sided coatings with anti-reflection coatings
ZWO Duo-Band Filter Technical Specification
Size: Standard 1.25”
Thickness: 1.85 mm
Bandwidth: HA (15nm) OIII (35nm)
Surface quality: 60/40 (Refer to MIL-O-13830)
Schott substrate material
More than 90% transmission at major OIII line 486.nm1, 496nm and 501nm.
More than 80% transmission at Ha line 656.3nm
Note:The incoming light transmitted through the filter should be perpendicular to the filter, or the incident angle should be less than 8°. Therefore, this product is not suitable for wide-angle or ultra wide-angle lenses.
Test Results
Images captured with ASI color cameras and Duo-Band Filters. You can see that the potential for deep space photography in strong light polluted areas is vastly improved with the Duo-Band filters.

Narrowband filter does not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.
It can reduce the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
