Optical Filters for LED Illuminated Displays

NVG Compatible & NVIS Compliant

Filter Choices for Many Different Applications

White, green, and red LEDs with certain spectral emissions can be filtered with our High Temperature Polymeric (HTP) filters to produce displays that comply with various NVIS color coordinates and NVIS radiance (NR) specifications as described in MIL-STD-3009.

We list a variety of standard sizes as a reference and we can machine most of our filter types to meet your specific dimensional requirements.

Please note that stray unfiltered light emitting from the bottom of the LED can cause NVIS radiance (NR) to fail. Potting may be required to light-seal the assembly.

Don’t hesitate to contact us for adhesive and opaque potting material recommendations best suited to your application.
