Abstract
An Ebert spectrometer is described with regard to its design, construction, and performance. It is intended to cover the 500–20 cm-1. region, and has so far been tested between 500 and 150 cm-1, where a resolution of 0.5 cm-1 is uniformly attained. The advantages of the Ebert optics in the long wavelength infrared are that they lead to a compact, simple, and convenient instrument for this difficult region of the spectrum, the performance of which is at least equal to that of the more elaborate instruments.Keywords
