Anti-halation cathode glass window (AVG) is a type of special and key material used in the super G II and G Ill night vision devices, which has characteristic of high transmission for UV to visible light, and high-absorption layer. This layer prepared by a special process has a very strong absorption to stray light. Photoelectric glass can eliminate flare and improve clarity of night vision devices.
