Night Vision NVIS Filters

Advanced Filters for Night-Vision Display CompatibilityBV-NVIS-A1000 series

Near Infrared (NIR) cut-off Night Vision filters are used in various applications and can be found in many devices which are used in everyday life. However for more demanding applications in display or image sensing where natural colours are required specially designed filters are required. Brinell Vision NVIS-A1000 range of filters provide outstanding visible transmission along with high levels of blocking to meet stringent radiance limits due to the steep NIR cut-off & class-leading visible transmission. Our filters are used in some of the most advanced applications in display and sensing systems on land, air and space. The BV-NVIS-A1000 range is designed to work in challenging environments and is optically stable at extreme temperatures and humidity levels.

Applications:

  • NVIS Compatibility for LCD panel displays
  • Radiance to Mil-85762A standard
