Overexposure Protection 
Cameras that are exposed to room light or other continuous light sources will quickly 
become saturated. This most often occurs when operating without a shutter. If the camera 
is mounted to a spectrograph, close the entrance slit of the spectrograph to reduce the 
incident light.  
Note: If the CCD is cooled to low temperatures (below -50°C), exposure to ambient 
light will over-saturate it. This may increase dark charge significantly. If the camera 
remains saturated after all light sources are removed, you may have to bring the camera 
back to room temperature to restore dark charge to its original level.
