Purpose of the development: Oversized windows of sapphire (method STC) are designed for use in infrared optics and manufacturing transparent armor.

Recommended application field: Used in optics, optoelectronics, microelectronics and medicine.

Technical characteristic: Specifications: Sizes, up to 350 mm diameter, thickness up to 40 Precision manufacturing, mm The dimensions ± 0,05 thickness ± 0,05 Blocks, doubles, twin layers and cracks, inclusions, visible under polarized light is not allowed Flatness <2-3 on a 25 mm (633 nm) Polished surface roughness (Ra), A 2 to 100 The quality of the polished surface of standard USA MIL-0-13830 S/D-80/50, 60/40, 40/20, 20/10 Transmission coefficient (): The visible and infrared region of the spectrum (up to 4.5 m) 85-87 UV region of the spectrum (0.2 m) 70 Internal stresses, kg/mm2 2 crystallographic orientation

Advantages over analogues: Sapphire is one of the most promising materials XXI century thanks to a unique combination of properties - it has a high transmittance in the ultraviolet, visible and infrared regions of the spectrum, high dielectric properties, has high hardness, wear resistance and thermal conductivity, radiation and chemical resistance, bioinerten.

The development stage readiness: Introduced in production

Technical and economic effect: In optoelectronics - the most efficient production of electroluminescent light sources, which are set lighting parameters 14-15 times greater than incandescent bulbs. In these devices, the sapphire is used as the substrate for light-emitting layers of different compounds, including gallium nitride and its solid solutions. According to experts, this is one of the most energy-efficient technologies of today. The world market for a new generation of light sources by 2015 is estimated to be nine to ten billion dollars. Another promising area is the use of sapphire optics, which works in extreme conditions. There is no alternative to sapphire material and replaces quartz. This equipment, which uses high pressure and corrosive environments, projection TV, the scanner cash registers and so on. Unique field of sapphire - aerospace engineering and transparent armor. In these areas, using sapphire windows are usually larger - 200 mm in diameter or more.
