Abstract
The multiple internal reflection accessories for internal reflection spectrometry described here utilizes a novel approach to match the round beam size and shape from a conventional FT-IR spectrometer to the typical rectangular IRE aperture. Its transfer optics distort the beam entering and exiting the IRE so that the cross-section of the beam is matched to that of the standard rectangular aperture of the IRE. This configuration reduces energy losses, eliminates the need to aluminize the edges of the crystal, and reduces spurious peaks from the adhesive or O-rings used to conventionally mount the crystal.
