All color models are equipped with an optical filter to
eliminate the influence of infrared light hitting the
sensor. Please be advised that, as a side effect, this fil-
ter reduces sensitivity in the visible spectrum. The opti-
cal filter is part of the back focus ring, which is
threaded into the C-Mount.

B/w models are delivered with a sensor protection
glass mounted in the back focus ring to ensure maxi-
mum sensitivity. In certain applications and depending
on the lighting source and optics, the use of either IR
blocking or IR passing filter may be required to improve
the image quality.
