KWY280D-21/31 (Gen2+&3) Night vision binocular
product description:
Product description：
KWY280D-21/31 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 is connected with a special binocular connector to become a binocular binocular night vision device, and can also be disassembled as two monocular night vision devices. The night vision instrument is equipped with an infrared auxiliary light source and an automatic anti glare protection system.
