Purpose of the development: Manufacture of optical crystals of germanium blanks infrared optics elements.

Recommended application field: Preforms for optical elements (windows, lenses, etc.).

Technical characteristic: Calibrated rods and plates with a diameter up to 250 mm. Blocks cuboid up to 160x160x60 mm3. The coefficient of the optical absorption of crystals - to 0.02 cm-1. Spectral range from 2 to 11 microns. The optical transmittance is not less than 46.5% at room temperature. The thickness of the polished samples - 5mm. Infrared light scattering does not exceed 1.5%.

Advantages over analogues: Feature crystals: new impurity composition (crystals contain no antimony as the dopant, which is normally used), which leads to an improvement of a number of parameters infrared optics elements made from such crystals.

The development stage readiness: Ready for application
