Sol-gel technology of obtaining think silica gel glasses


Гель-стеклоThis know-how allows obtaining plates of a quartz glass without melting and cuting of monoliths on separate plates. Think silica gel glasses (≤1 mm) are intended for manufacturing of optical elements, screens displays, light filters with selective absorption of light radiation over a wide wavelength range, etc.

THE AREA OF APPLICATION

  • Think silica gel glasses can be applied in optics, quantum electronics, microelectronics, spectacles of different types, screens TFT- displays, optical windows in devices, plates for a microwave microcircuit, etc.

ADVANTAGES: Excellent optical, physical-mechanical and chemical properties

VARIANTS OF COOPERATION: Delivery of consignments of a glass, transfer of sol-gel technologies of their manufacture on the license basis, development of new kinds of glasses.
