Very Rare - 4th generation night vision devices with autogated/filmless tubes LIMITED Quantities Available!! ATNs Autogated / Filmless IITs improve night operational effectiveness in dynamic lighting conditions such as those experienced, for example, in night operations in urban areas. The filmless micro channel plate provides a higher signal-to-noise ratio than standard Gen 3, resulting in better image quality under low-light conditions. An Autogated power supply further improves image resolution under high light conditions and a reduced halo effect that minimizes interference from bright light sources.
