34 PIXIS System Manual Version 2.C
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.
