The graphs below show how noise performance is affected by APD gain. They are computed curves for
guidance only. Curves are noise spectral density in W/Hz
ration). Lower curves (with circles) are dark noise. Upper curves (with boxes) are NSD at full bandwidth.
Modules normally have gain set to 100 for small and 50 for large detectors. Gain adjustments is possible and is
explained in the handbook.
