IR cut filter
All Prosilica GX color models are equipped with an infrared cut filter (IR filter). This
filter is employed to prevent infrared wavelength photons from passing to the
sensor. In the absence of IR filter, images are dominated by red and incapable of
being properly color balanced. Monochrome models do not employ an IR filter.
The figure below shows the filter transmission response for the IRC30 cut filter
employed in color Prosilica GX cameras.
