Passive glasses in surveillance systems

The analysis of the possibilities of determining the spectrum of electromagnetic radiation from celestial objects using the optical-electronic system of the telescope using CCD receivers is carried out. It is shown that with the introduction of new CCD-type receivers into photometry, the efficiency of observing celestial objects has significantly increased, but despite the positive result, it is necessary to eliminate problems when registering objects with weak radiation during measurements. The purpose of the article is based on the results of experimental studies of thermomechanical and optical properties of multicomponent glasses to provide a justification for the introduction of new materials with a wider transmission range of radiation in various spectra as elements of optical systems of telescopes. In the course of research of new optical materials using the spectroscopy method, optimal compositions of multicomponent glasses were found, allowing to perceive electromagnetic radiation from celestial bodies in various ranges of the infrared spectrum. In conclusion, the results of the study are presented, showing that the introduction of indium and lead fluorides into the composition of multicomponent glass significantly increases the transmission range, which will increase the efficiency of the optical system when using these materials for its elements.
