ZWO
ZWO ASI432MM Mono Camera
$949.00
Large monochrome pixels and a global shutter
The ASI432MM uses a Sony IMX432 global-shutter sensor. Its 9 µm pixels and fast monochrome readout suit solar, lunar and planetary imaging.
Large collection area
The 1.1″ sensor has a 1608 × 1104 array with a 97 ke⁻ full-well rating.
Record rapid sequences
ZWO specifies 120 fps at full frame in 12-bit mode.
Compare spectral response
ZWO quotes a 79% peak and publishes the monochrome QE curve.
Expose the whole frame at once
The global shutter exposes all pixels together. ZWO uses this sensor design to avoid the rolling-shutter effect when the scene moves during capture.
Sensor curves and setup diagrams
Full well
The charge a pixel can hold before saturation. The curve starts around 97,000 electrons and falls as gain rises.
Conversion gain
The electrons represented by one digital count. ZWO marks the point near one electron per count at gain 272.
Dynamic range
The span between the noise floor and saturation. The range rises back near 12 stops at the transition, then declines.
Read noise
Noise introduced when the sensor is read. The read-noise step is marked at gain 140, where the plotted noise drops to about 4 electrons RMS.
Relative spectral response
The relative monochrome response is strongest around 600 nm and falls towards 1000 nm.
