Abstract

The infrared dispersion-interference filter assembly comprises a dispersion system and an interference system which are arranged between support layers. Interconnecting layers are arranged between the dispersion system and its support layer and between the dispersion system and the interference system. These interconnecting layers and those facing the lower-refraction layers of the interference system consist of the same non-hygroscopic material, e.g. KCl USE/ADVANTAGE - Filter mainly for providing monochromatic light. The arrangement increases mechanical strength and optimises stability of characteristic spectral lines under varying environmental conditions and the action of the air included during assembly.
