Crystalline quartz as a far-infrared beam splitter for Fourier transform spectroscopy.
We show that room-temperature, crystalline quartz is a useful material for a beam splitter for spectroscopy in the far infrared, ~60-mum wavelength and longer. We compare such a beam splitter with the traditional far-infrared candidates: Mylar, polarizing, and lamellar beam splitters.
