Prosilica GC Technical Manual V2.1.0

Filter

All Prosilica GC 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 GC cameras.
