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