Petrov D. Technology of infrared optical color glasses for special purpose

The object of work is infrared optical colored glasses and technological parameters of its production. The purpose of the study is to develop the composition and technological parameters for obtaining a new type of optical colored glass with a high transmittance (at least 65%) at a 1060 nm point and at the lowest possible transmittance at 950 nm point for use in modern optoelectronic devices to improve the accuracy of OЕS. Research methods ‒ determination of physical, chemical, optical and operational properties of model glass and thin film coatings were carried out using by standard and special techniques. As the result of theoretical and bottom line it has been established the theoretical substantiation and implementation of the technology of optical colored glass with thin-film coatings is realized. On the basis of the developed scientific provisions optical color glass with selective transmission in the infrared range was created and the technological parameters of its industrial production were obtained. The novelty is the mechanism of glass coloring in the system of R2O-PbO-SiO2 with a complex of colorants Cr2O3-Mn2O3 was determined. The peculiarities of the influence of heat treatment and the composition of the complex colorant on the valence state of Mn2O3 with the presence of residual FeO (Fe2O3) in glass are revealed. The results of the scientific work were implemented at the State Enterprise "Izyum Instrument-Making Plant". As a result of the introduction 750 kg of optical colored glass with a specific economic effect of 746.22 UAH/kg was obtained. Scientific results of work can be used at the enterprises of the instrument-making branches and at the enterprises of optical glass production, as well as it can be used at higher educational institutions in the training of specialists in the technology of refractory nonmetallic materials.
