Abstract

The infrared transmission of relatively thick polished diamond films has been measured by Fourier transform infrared spectroscopy. Transmission of 70% at 10 micrometers for a 198 micrometers thick film and 69% at 10 micrometers for a 338 micrometers thick film is reported. By analysis of the interference fringes in the transmission spectra, it is estimated that, for a wavelength of 10 micrometers , the index of refraction of the films is comparable to that of a Drukker IIa window. The absorption coefficients of two films at the maximum of the one phonon absorption region are compared with the hydrogen and nitrogen content of the films and the Raman spectra of the films.
