Working since 1988, Kopp Glass, Inc. has developed the widest range of filters available to provide security and/or compatibility with the latest night vision imaging systems. All filters are manufactured in the United States, are of single layer construction, comply with the specifications outlined in MIL-L-85762A, Method 507.3, Procedure 3. Filters are designed for two or more thicknesses in the 1 to 4 millimeter range.

   Below is a list of available glasses.  They are linked to pages containing approximate spectral curves and information on them. Reported chromaticity coordinates and NVIS Radiance values are based on measured transmittance data and theoretical calculations of the spectral output of an incandescent source operating at a given color temperature. The calculated lamp output has been corrected for the emissivity of a tungsten filament. Actual data acquired by independent testing laboratories is available upon request.

Note:  To reduce file size, many of the graphs have been reproduced over the originals.
