The “Gain” and “Offset“ field
The default gain setting is “1.0”. You may change the gain up to factor 3.0 (or higher) in steps of
1/10
th
. Note that the dark offset will increase and dynamic range will not be improved! For good
image quality do not increase gain more than factor 2, because the noise is also amplified.
“Gain value” allows finer adjustments than “gain factor”.
“F” , “U” and “H” version of svs11002/16000:
Note that the CCD has 2 outputs. Therefore there are a “right” and a
“left” image half. If you use the slider both channels are amplified.
However depending on the amplifications there might be different values
necessary in order to make both channels equal. Fine tuning in “Gain
Value” is necessary. There are about 768 possible steps to adjust. It is
still possible to have 1-2 counts difference between both image halfs.
This is NOT a camera problem and must be adjusted by an experienced
user. Same is true for the offset.
Dark level offset adjustment is possible. Please note that factory adjustment is optimized for S/N
ratio and sensitivity. You may lose dynamic range. Alter only if you operate at high temperatures
like +40 °C. It can be altered for each channel separately.
The “Snapshot Button” (svs16000 only)
Will read ONE image only if camera is set to “free running” or” triggered with internal expo
control” mode.
