Results of imitation experiments on effects of charge exchange atoms bombardment on optical properties of metallic mirrors (in the spectrum range of 200–800 nm) are presented. The long-term sputtering of mirror samples made of stainless steel, copper and hot pressed beryllium have been carried out with plasma ions (H + , D + , He + , or Ar + ) of keV energy range. It was shown that in the case of a stainless steel mirror, the sputtering of a layer of ∼2 μm thick did not lead to significant change in reflectivity. As to a copper mirror, a noticeable change of reflectivity was observed after sputtering of ∼0.7 μm layer using He + ions. The highest rate of degradation, especially in the UV region, was found in the case of beryllium mirrors.
