Where Night Vision Imaging Systems (NVIS) are employed, all components that emit light must be designed and tested for compatibility. MIL-STD-3009 / MIL-L-85762A specifies the light characteristics that are for components that must be used in an NVIS environment. Avionics, Displays & Indicators as well as cabin and external lighting must be designed and certified to be compatible with NVIS. Our OL 770-NVS and OL 750-NVG spectroradiometer systems are used by top avionics and aviation lighting providers to assure compliance. Likewise, various commercial Aviation Navigation and Anti-Collision beacons must also be NVIS-Friendly
