This can result in CCD images with visible quadrant (like a chess board
pattern).
Under the
Camera
menu (Figure 2-3),
Set Bias Levels
routine automatically
measures and sets the bias for each quadrant. The bias setting is written to the
First Light Controller. This will remove the majority of the image contrast from
quadrant to quadrant in an evenly illuminated flat field image and maximize the
dynamic range.
The
Set Bias Levels
should be run before the linearization procedure (next
section) and after the camera is cooled. It is not necessary to run
Set Bias
Levels
again.
When running this routine, it does not matter if the viewing screen is raised or
not since the automatic procedure blanks the beam on the CCD as needed.
