The optical properties of TlGaS2, TlGaSe2, and TlInS2 crystals have been investigated through the transmission and reflection measurements at room temperature in the wavelength range of 400-1100 nm. These measurements allowed determination of spectral dependence of the refractive index for all crystals studied. The dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single-effective-oscillator model. The refractive index dispersion parameters: the oscillator energies, the dispersion energies, and the zero-frequency dielectric constants and refractive indices were determined.
