cut-off colored filter long wave short wave coating high transmission color optical filter

  • Longpass Filter - Newport

    Long wave pass edge filters (longpass filters) have a region of rejection on the short-wavelength side of the cut-on wavelength. These filters are defined by a cut-on slope establishing the transition between a region of high rejection and a region of high transmission that is provided by thin-film coatings or absorptive colored glass.
