Description in English
Main aims of submitted project are the following: 1. Total optical characterization of single coating layers used in multilayer systems, that means coating layers of Al2O3, MgF2, HfO2 and SiO2 materials. 2. Development of antireflection coatings on glass substrates with required values of transmittance for wavelengths 213 nm and 248 nm and for normal angle of incidence. Fabrication of samples on the basis of design and optical characterization of these samples. Modification of technological conditions of coating and production of optimized samples. Control of achieved optimization through measurement of spectral dependence of reflectance and transmittance. 3. Development of mirrors with high reflectance on glass substrates with required average reflectance values for wavelengths 248 nm and 213 nm and for 45°angle of incidence. Fabrication of samples on the basis of designs together with optical characterization. Modification of technological conditions of coating and production of optimized samples. Control of achieved optimization through measurement of spectral dependence of reflectance. 4. Development of beam splitter on glass substrates with required p-value of transmittance or for average transmittance for wavelength 248 nm and with required s-value of reflectance for wavelengths 630 nm – 670 nm and for 45°angle of incidence. Fabrication of samples on the basis of design together with optical characterization. Modification of technological conditions of coating and production of optimized samples. Control of achieved optimization through measurement of spectral dependence of reflectance and transmittance. 5. Measurement of internal tensile stress and parameters to characterize mechanical properties of coating layers and multi-layer systems for assessment of lifetime joint with control of surface uniformity of their optical parameters.
