Conversion Factor
The conversion factor defines how many charges (electrons),
generated by light in each pixel, are necessary to generate one count
(one intensity level) in the digital image. Therefore, the conversion
factor describes the gain when converting electrons into a digital
value.
The pco.ultraviolet has two conversion factors namely 0.8 e
-
and
1.4 e
-
/ count which both can be used in
1x1 (full resolution)
and
higher binning modes. As mentioned in
binning is available for
the pco.ultraviolet. The usable extended fullwell-capacity rises in
binning mode from 14000 to 24000e
-
. In
1x1 (full resolution)
it
makes sense to keep 0.8 e
-
/count; changing the conversion factor to
1.4e
-
the high dynamic of 16384 grey steps is not usable.. In higher
binning modes
you can use both conversion factors: Having a
lowlight scene the 0.8 e
-
/count mode helps to spread the low image
information content – in normal light scenes it makes sense to use
1.4e
-
/count for full dynamic availability.
