Abstrakt: Experimental results on the action of an accelerated Xe ion flux on borosilicate glasses of K208 and CMG100 types at grazing incidence angles of 60° and 75° are presented. It is revealed that a microrelief is developed on the CMG100 surface and, as a result, the optical properties of the glass are altered. The microrelief's average height is 500-600 nm at an erosion depth of 7.1 μm, and in this case optical losses are 60%. The microrelief is developed only at an incident angle of 75°. At an incident angle of 60° surface irregularities are smoothed, at the same time whiskers and pyramidal hillocks are formed. In this case the optical properties of the glass vary insignificantly. A microrelief is also formed on the K208 surface, the irregularity height is no more than 60-80 nm which insignificantly influences the optical properties of the glass. [ABSTRACT FROM AUTHOR]
