Abstract
We describe the design, fabrication, testing, and performance of a two -layer free-standing beam splitter for use in far-infrared Fourier tra nsform infrared spectrometers. This bilayer beam splitter, consisting of a low-index polymer layer in combination with a high-index semicond uctor layer, has an efficiency that is higher than that of the best co mbination of four single-layer Mylar beam splitters currently in use f or spectrometry from 50 to 550 cm(-1).
