Paper Abstract

The possibilities of controlling production processes and products by means of optical filter devices are largely determined by the quality of the filters used. The basic requirement for infrared filters designed for selecting radiation of heat sources is that they be high contrast. A promising method providing a simple and reliable constructive solution of this problem is the combining of interference systems, consisting of a small number of layers and forming a transmission band in the filter transmission region, with a scattering system effectively attenuating the background radiation in a wide spectral region.
