6.3 Cooling system
The cooled ASI1600 cameras 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 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 -40
℃
~-45
℃
below ambient.
Here is a dark current test result of 1600 Cool sensor at various temperatures.
6.4 Back focus distance
When the attached 11mm T2 Extender is removed the optical distance from the sensor to the
camera body is reduced to 6.5mm.
6.5 Protect Window
There is a protect window before the sensor of ASI1600 camera.
It’s an AR-AR coated BK7 glass, diameter is 32mm and 2mm thick.
