This IR-blocking filter must not be confused with heat-resisting protection filters for projectors or spotlights. Instead, it is intended for use as protection for IR-sensitive CCD sensors or in the light path of illumination devices with low thermal characteristics. It suppresses infrared radiation ≥780 nm. Because it gradually begins to absorb infrared radiation at 600 nm, long-wave red light is slightly weakened, so that this filter has a subtle green tint. But in CCD applications, this can be readily corrected electronically. Its filter factor is approximately 1.2.
