5.3 Cooling system
The ASI071 camera have a robust, regulated cooling system, which means that the camera sensor
can be kept at the desired temperature throughout your imaging session. The super low readout
noise, combined with efficient cooling and adjustable gain setting, allows you to do short or lucky
DSO imaging unlike the traditional CCD cameras which need very long exposure for each frame.
However, keep in mind that cooling won’t help with very short exposure such as less than 100ms.
The lowest temperature that can be set is -40
℃
.
Here is a dark current test result of ASI071 Cool sensor at various temperatures.
