NVIS Compliance in an Illuminated LED Panel: How Spectral Output Is Controlled for NVG Compatibility
Night vision goggles are sensitive to a broad spectrum of radiation, including the near-infrared wavelengths that dominate the emission of many standard light-emitting diodes. An illuminated panel in an NVG-compatible cockpit must therefore be engineered so that its spectral output falls within the limits defined by the applicable NVIS standard - typically MIL-L-85762A - without degrading the visible illumination qualities that make the panel legible to the unaided eye. Achieving both objectives simultaneously requires a precise understanding of LED emission physics and the filtering and drive strategies available to control spectral output.
