    Technical Information

    Our most popular near-IR blocking filter for inside-the-camera applications. Also referred to as an “infrared cut filter”, these filters limit the amount of infrared radiation that reaches delicate CCD and CMOS sensors. Near-IR blocking is unusually exceptional in the case of these filters. CCD/CMOS imagers are very sensitive to infrared radiation and, often, deep red wavelengths as well. Using a SP645 filter will reduce or prevent a reddish, washed out coloring of the final image. These filters are 1mm thick.

    • Useful Range : 400-640nm
    • Cut-off Wavelength 50% T : 645nm
    • Tolerance : +/- 10nm
    • Peak Transmission : ≥90%
    • Surface Quality : 40/20
     
     
    Note: Midwest Optical filters are considered to be special order items and are thus not returnable.
