iKey offers LED backlit keyboards that are compatible with night vision goggles. The NVIS Green B compliant iKey keyboards include filters that remove unwanted light interference between their illuminated keys and night vision goggles. iKey's keyboards have been third party tested and approved for NVIS Green B compliance. They are applicable in military, law enforcement and emergency medical operations that require some form of effective visual enhancement at night. The color and optical properties of iKey's filtered rugged keyboards also comply with MIL-STD specifications and standards for night vision goggle compatible lighting displays. Because iKey keyboards come in compact and mountable models with NVIS compatible LED backlighting, they can be successfully implemented into tanks, airplanes, submarines, helicopters and many custom projects.
