Kopp Glass is the industry leader for Night Vision Goggle (NVG) compatible colored filter glass having pioneered the development of the extensive product line in the 1980's. Today, Kopp is focused on meeting the challenges associated with the adoption of Light Emitting Diode (LED) technology used in aerospace applications. Kopp's product line has been expanded to include many new LED compatible NVG filter glass offerings that are also lower weight with reduced nominal thickness requirements.
Color uniformity is critical for NVIS compatible lighting environments. If the color is not uniform it can cause undesired distractions and color saturation can lead to eye fatigue. MIL-STD-3009 specifies the acceptable color parameters and NVIS radiance requirements for various NVIS lighting applications. However, within the MIL-STD-3009 acceptable color circles, the color will appear varied. For this reason Kopp has engineered its product line to meet narrowed ranges within the acceptable color specifications resulting in a superior filter product line with consistent and uniform spectral properties.
