Abstract

The infrared transmittance of a high-optical-quality chemical vapor deposition (CVD) diamond sample was independently measured by The Johns Hopkins University Applied Physics Laboratory, Rockwell International, and Texas Instruments, Inc., from room temperature to 780 K.At0.75 mm thick, the sample is one of the thickest high-optical-quality CVD diamond samples produced so far. Measurements were taken with both dual-beam grating spectrometers and a Fourier transform spectrometer so that experimental artifacts of a particular instrument could be identified and reduced. The data sets were in good agreement from room temperature to 780 K. This work definitively establishes the high-temperature optical properties of CVD diamond.
