Thin film of Zinc Selenide (ZnSe) has deposited by thermal evaporation method onto pre cleaned glass substrate under high vacuum condition. The deposited ZnSe film has been characterized for optical and dispersion analysis from absorption spectra within the wavelength range of 300 nm-1100 nm which was recorded by using UV-Visible spectrophotometer. The optical parameters (optical band gap, Urbach energy, steepness parameter, complex dielectric constant, extinction coefficient and refractive index) have been calculated from absorption spectra. The dispersion parameters (oscillation energy, dispersion energy, oscillator strength, oscillator wavelength, static refractive index, high frequency dielectric constant, lattice dielectric constant and plasma resonance frequency) have been analyzed by Wemple-DiDomenico single oscillator model.
