Night Vision Imaging System (NVIS) LEDs and Filters NVG DISPLAY COMPATIBILITY PER MIL-L-85762A and MIL-STD-3009 The LEDs in a display heavily influence its color, contrast, and NVIS radiance (NR) properties. White, green, and red LEDs with certain spectral emission can be filtered with our High Temperature Polymeric (HTP) filters to produce displays that comply with various NVIS color coordinates and NVIS Radiance (NR) specifications described in MIL-STD-3009. Color and NVIS Radiance Meeting both color and NVIS Radiance limits can be challenging. Each application is unique and always involve certain constraints, such as space limitations or production methods, that may require a specific approach in order meet compliance. Light Sealed (LS) SMD Type LEDs are 100% encapsulated and emit only NVIS filtered light and therefore meet color and NR limits. Other NVIS filter/LED assemblies may have a smaller profile but may require opaque potting in order to eliminate stray unfiltered light in order to meet NR limits. Please don't hesitate to contact us to help find a solution to meet your particular application.
