Abstract
Spectroscopic ellipsometry measurements were performed in the region 0 .5-5.0 eV on single crystals of cuprates with incommensurate-type stru cture. Three components of the dielectric function were determined by making use of the measurements made on two developed planes of orthorh ombic crystals. The main optical transitions contributing to the optic al response of the crystals of various chemical compositions and struc tural parameters were revealed. The relationship between optical aniso tropy and crystal structure was analysed.
