Linear optical properties of the Zn_{1-x}Mg_{x}Se (0 ≤ x ≤ 0.4) alloys have been studied using reflectance, spectroscopic ellipsometry and photoluminescence measurements. The refractive indices of Zn_{1-x}Mg_{x}Se epilayers were investigated as a function of Mg composition (0 ≤ x ≤ 0.4). The energies of band gap E_{g} and spin-orbit splitting E_{g}+Δ, have been determined. These energies are shifted gradually to higher values with increasing Mg content.
