Plastic NVIS Filters

Drawing on more than 30 years of experience in NVIS-compliant light filtering, we have engineered Korry Nightshield plastic NVIS filters for reliable, cost-effective new installations and retrofits in commercial aviation, medical evacuation, search and rescue, law enforcement, and defense

Nightshield filters are a simple way of keeping users of night-vision devices (NVDs) safe. Our filters can be applied to any light source to regulate its infrared emissions, preventing interference with a pilot's or ground-equipment operator's goggles.

NVDs create a picture of the nighttime environment by amplifying ambient infrared energy, so unfiltered light sources in proximity can cause blooming and flaring, potentially disorienting NVD users. Nightshield filters solve this problem. They also help conceal the users' location by making their lighted equipment more difficult to observe through NVDs at a distance.

Additional advantages include:

  • Engineered for temperature extremes from -55 to +85 degrees C, where many other plastics fail.
  • Available in a variety of colors, thicknesses, sizes, and other options, to filter anything that emits light: lamps, indicator lights, legends, screens of every type, including touch screens.
  • Ideal for fixed-mount, hand-held, or carry-on equipment, everything from cockpits and dashboards to laptops, smart pads, smart phones, even defibrillators.
  • Available in flexible sheets that can be cut with scissors for quick retrofit of air or land applications.
  • Suitable for the toughest environments and qualified to many Mil-STD specs.
  • Available in standard dual-use configurations (EAR-99), with no export license required.
