The practice of use of diagnostic mirrors inside the fusion devices revealed the appearance of a deposit on the mirror surface. Such deposit is a result of condensation of the erosion materials of those inner components that are subjected to the strongest plasma impact. Another reason for deposit growth is the wall conditioning procedures like carbonization and boronization. Appeared on the diagnostic mirrors and windows the contaminating films deteriorate the optical properties of these diagnostic elements, i.e., the mirror reflectance and window transmissivity. The object of this paper is to investigate an influence on reflectance of metal mirrors of thin films of the materials that are most probable in fusion devices under operation (boron and carbon) or can be promising in a fusion reactor (beryllium).
