Abstract

Precise measurement of the refractive index of chemical vapor deposition (CVD) ZnSe with the Fourier-transform interference refractometry method from 0.9 to 21.7 μm (from 11,000 to 460 cm 1 ) with 0.1 cm 1 resolution is described. For this measurement, structurally homogeneous ZnSe plates were grown on a substrate with an optimized temperature increase. Using three ZnSe plates of different thicknesses, we managed to raise the measurement accuracy of the refractive index up to 2 × 10 5 (being nearly 1 order of magnitude better than the available data) in the near IR and most of the middle IR wavelength range from 0.9 to 12.5 μm (wavenumber range of 11 , 000 800 cm 1 ) and up to 1 4 × 10 4 in the 12.5 21.7 μm ( 800 460 cm 1 ) region. The experimental results are approximated by a generalized Cauchy dispersion function of the 8th power. Spectral wavelength dependencies of the first- and second-order derivatives of the refractive index are calculated, and the zero material dispersion wavelength is found to be λ 0 = 4.84 μm .
