Vacuum evaporated crystalline films of Zinc Selenide (ZnSe) have been characterized by using optical spectroscopy (especially absorption and transmission spectroscopy). Crystalline ZnSe films have been deposited by vacuum evaporation technique on highly clean glass substrates and their optical properties (energy band gap, refractive index and extinction coefficient) have been studied. The energy band gap (Eg) of the films has been calculated from absorption spectra by using Tauc relation. The transmission spectra in the spectral range 400-850 nm has been used to calculate the refractive index (n), extinction coefficient (k) and wavelength dependence of n and k of the films have been studied. Optical spectroscopy of the films have been done with the help of the Hitachi spectrophotometer model U-3400.
