Product Description
DT – NH8XX is based on the latest ophotoelectric technology research and development of new products,,The instrument adopts the high-performance generation ii/three image intensifier, with excellent performance, small volume and weight ,light, clear imaging, simple operation, high cost performance, and by replacing the objective lens (or connecting multiplier lens). It can change magnification and so on. The product can be connected with digital cameras, cameras and video cameras. cooperate with the gun aiming fixture can hang gun use, also can be used alone. The night vision instrument is equipped with an infrared auxiliary light source and an automatic anti glare protection system. The product practicality is strong, can be suitable Used for night without lighting military observation, coastal defense reconnaissance, public security environment Monitoring, forensics, customs anti-smuggling, etc., the public security department, the armed police force, special police forces, and the guard patrolling the ideal equipment.
