• Based on the transmittance spectra modeling, spectroscopic methods were developed to determine the optical constants of glass materials including extinction coefficient and refractive index. The transmittance spectrograms of ZnSe glass slabs at normal incidence with different thicknesses in the infrared wavelength 0.83--21 μm were measured by a Bruke V70 Fourier transform infrared (FTIR) spectrometer. These values were introduced into spectroscopic methods to calculate the optical constants of ZnSe glass. The results showed most of the optical constants of ZnSe determined by the new method had a good agreement with previously data, indicating that the spectroscopic methods can be used to determine the optical constants of glass materials in most infrared spectra.
