IR cut filter: spectral transmission
All Prosilica GC color models are equipped with an infrared block filter
(IR filter). This filter is employed to stop infrared wavelength photons
from passing to the imaging device. If the filter is removed, images will
be dominated by red and cannot be properly color balanced.
Monochrome Prosilica GC cameras do not employ an IR filter.
The figure below shows the filter transmission response for the IRC filter
family from Sunex. The cameras utilize the IRC30 filter.
