Paper Abstract

There are presented some solutions of anti-laser absorption-interference filters, satisfying the demands of high transmission in the visible range, enlarged resistance and improved work comfort at longer usage. In order to increase the total transmission is was used the anti- reflecting coatings onto the glass surface. Besides the contrast increase the work comfort is improved. The anti-reflecting layers are necessary in case of using the large power lasers due to the possibility of reflection of large intensity radiation from the filter surface. A selective reflection of light by thin-layer interference pile was used in construction of anti-laser filters for several wavelengths. The absorption-interference filter was elaborated for I and II YAG:Nd laser harmonics. By depositing the CUT-OFF type thin-layer filter onto the infrared and NIR filters, virtually brightened image, high rising of contrast and the final green color well accepted by eye were obtained.
