Abstract:

In this study, interference filters based on Fabry–Perot interferometers and the principle and effect of attenuated total internal reflection were analyzed. In addition, the characteristics of a MgF₂ interference filter and glass-grade STF2 are provided. A transmission half-width of up to 4 nm at a contrast of 5.3×10⁻⁵ was achieved for a given filter constructed from three interference layers. It was established that the examined filter could be used as a polarizer.

Keywords:
