exposure or lucky DSO imaging, unlike the traditional CCD cameras which need very long
exposures for each frame. However, keep in mind that cooling won’t help with very short
exposures such as less than 100ms. The lowest temperature that can be set is -30
℃
.
6.4 Protect Window
There is a protect window before the sensor of ASI290 camera.
Our ASI290MM and ASI290MC comes with the D21 AR window, thickness is 1.1 mm.
While ASI290MM-COOL and ASI290MC-COOL has the D25 AR window, thickness is 3 mm.
6.5 Analog to Digital Converter (ADC)
The ASI290 camera records in 12bit ADC and 10bit ADC. You can image at a faster fps rate if you
choose to use 10bit ADC (high speed mode). This camera also supports ROI (region of interest)
shooting, and this smaller ROI has faster fps.
Here is the maximum speed of ASI290 running at 10bit ADC and 12bit ADC.

6.6 Binning
The ASI290 camera supports software bin2 mode. You should use 10bit ADC. We recommend
customer to use software binning if you don’t care speed.
