Coatings and hot mirrors
Reflect unwanted wavelengths with an interference coating or hot mirror. Define incidence angle and spectral limits for the actual light path.
Backlight Optics / IR Blocking Materials
Control the spectrum at the source.
Explore infrared-blocking coatings, polymer films, absorbing glass and formed filters for backlight integration. Chips, strips, caps and filter rails can be developed around selected LEDs and optical paths.
IRF items are development references requiring further definition and verification. Select the LED spectrum, filter construction, thickness, angle range, temperature and light sealing together. NVIS Class A/B, output color and finished-display radiance are separate requirements; no material alone establishes compliance.
