SP644 is one of several dichroic filters offered mainly for use as an internal infrared blocking filter in color cameras. This design offers an attractive price/performance option compared to other designs. Uniform blocking of near-infrared wavelengths out to 1100nm, uniformly high transmission across the visible range, and a 50% point in the middle of the red portion of the spectrum make this an ideal choice for cameras with typical CMOS sensor responsivity. SP644 is useful to achieve natural color rendition with superior response in the blue channel.

  • Cut-off Wavelength 50% T : 648nm
