The performance of the CompM4 is optimized for use with all generations of night vision devices (NVDs), but is especially suited for 3rd generation night vision technology. Aimpoint’s unique band-pass coating on the front lens reflects select frequencies of red light at near 100% efficiency in order to give the highest possible dot brightness with the smallest amount of energy while transmitting nearly 100% of light in the Infrared and near-infrared part of the spectrum to provide the clearest, brightest image possible when used with a 3rd generation NVD.
