3.3 Optical Window
The optical window used in front of the CCD is a BK7 with BBAR coatings on
both sides ensuring that no reflection will appear in your image.
3.4 Analog to Digital Converter (ADC)
The Analog to Digital Converter (ADC) is a 16-bit ADC. This means that your
Atik camera will allow you to record subtle levels of gray, providing you with
enhanced dynamic range when capturing an image.
3.5 Power Consumption
Your Atik camera was designed to have low power consumption: please see
the table in section 4 for details specific to your camera model. The 2.1mm
centre-positive DC input is compatible with a wide range of 12V DC supplies.
WARNING: If you have purchased the optional
mains power adaptor, please
note that it is for indoor or observatory use only. There is a risk of electric shock if the
adaptor is used in damp environments or outside. If in doubt do not use the adaptor
and consult a trained electrician.
3.6 USB Port
The Atik series 4 cameras use a USB 2.0 high-speed interface, allowing full-
frame image downloads in only a few seconds. A higher speed “preview”
mode is also present, providing roughly twice the speed.
3.7 Cooling
All Series 4 cameras have a robust, regulated cooling system, meaning that
the CCD is kept at the desired temperature throughout the observing session.
The very low readout noise, combined with efficient cooling, means that dark
frames are not necessary in most situations, allowing you to spend more time
imaging and less time taking calibration frames, but if very long exposures are
to be used or high precision data is required (exo-planet searches, for
example), dark frame libraries will be easy to maintain.
3.8 Replacing the desiccant
Your camera includes a high-performance molecular
sieve desiccant tablet which is used to avoid
condensation in the CCD chamber. Although this
desiccant will last a long time it may eventually need
replacement or recharging, in which case please follow
the instructions below:
- To replace the desiccant, open the desiccant port with the supplied
plastic interface and a screwdriver, take out the used tablet and replace
