The next software iteration
used a single gain array where gains could be calculated and stored
at 5 nm intervals. The use of a single gain profile proved impractical
as gain profiles had to be recalculated frequently primarily due
to changes in the composition of target backgrounds, e.g., HDPE
exhibits an auto fluorescence response to supplemental LED illumination
while SS does not. In the current software, users can select
among five named gain profiles and, if desired, recalculate one of
the three variable profiles by pressing the appropriate icon. The
gain profiles are graphed to allow users to better select the appropriate
gain array for use.
