Abstract
Night Vision Goggle compatible red lighting in which the red light does not adversely affect the gain of the night vision goggles yet is visible to the unaided eye. The red light is filtered by a filter which transmits at least about 80% of the visible spectrum within a range up to about 640 nanometers in wavelength and inhibits the transmission of 99.9% of said red light above about 720 nanometers in wavelength on the electromagnetic spectrum within the spectral sensitivity of the night vision goggles.
