We produce plates of various configurations: round, rectangular, oval, coated, wedges.

We manufacture plates used as optical windows for optoelectronic devices, protective glass, light filters, filters, substrates for mirrors and reticles, pressure glass, screen etc. according to the customer technical requirements.

The production of optical windows for EOPs is made from electrovacuum glass of own production, which allows to significantly reduce costs and price of windows in comparison with existing analogues.

The melting of the glass LK107 providing the resistance to the radiation has been developed for the manufacture of the plates to complete observant equipment.
