IRC30 filter
IRC30 filter
All Prosilica GE color models are equipped with an infrared block 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 cameras do not
employ an IR filter.
The figure below shows the filter transmission response for the IRC30 filter
employed in the Prosilica GE cameras.
