Abstract

The refractive index of a germanium prism was measured by two different laboratories for wavelengths in the 8–14-μm range. The sample was a single crystal of known purity and growth history. Index results from the two experiments agreed to within 0.0003 in agreement with the uncertainty analysis presented.
