Flight decks and other crewstations include a wide array of illuminated switches and indicators with various dimensions, colors, and lighting requirements. Retrofitting these environments to be night-vision compatible presents many problems.
Nightshield filters offer a consistent, highly adaptable, and cost-effective solution.
We manufacture Nightshield filters to your precise dimensional specifications, to fit virtually any illuminated switch or indicator. If you have special night-vision lighting needs, we can customize the filter recipe to meet your specification. We can also provide complete legends—integrating a Nightshield filter and nomenclature—to further simplify your retrofits.
The following table provides more detailed information for some common colors and light sources. Data include photopic transmission, color, and NR values (MIL-STD 3009, formerly MIL-L-85762A) within a normal range of properties for a specific application. These materials may also be enhanced by the addition of textured anti-glare surfaces, antireflective coatings, and transparent-conductive indium-tin-oxide (ITO) coatings.
To discuss your specific requirements with one of our specialists in night-vision optics, call Korry Electronics at 1-800-257-8921 (US only) or 206-281-1300.
