Critical reflectivit>r sr>ectra have been measured at room temr>erature on a singlecr>'stal of CuFeSz between 0.025 and 6 eV. The exrerimental results have t>eenused to calculate the or>tical constants, the dielectric constant and the absorptioncoefficient. There have been found an absorption band with peaks at 1.0 and2.1 eV and an absorption edge at approximately 3.2 eV. The band can be assignedto the charge-transfer transition from the valence band to the empty 3d statesof Fe, and the edge can be attributed to the commencement of the band to bandtransition. A schematical energy level diagram for CuFeS. is given from the result.
