Abstract:

The purpose of the work is to develop technical and production engineering measures and methods for the rapid manufacture of a Near Infrared Transmitting, Visible Light Absorbing Filter for the Infrared Searchlight ANVSS-3A, the 1 kilowatt type. The filter assembly to be manufactured consists of two glass cylinders, one or both tinted chemically, and each coated with a multilayer interference coating so that the transmission of visible radiation is minimized, while the near infrared transmission is maximized.
