Plane-parallel windows are used in optical devices as protective windows, light filter substrates, and compensators for spherical aberration. The use of wedge-shaped windows can be similar, and their specificity lies in the ability to deflect the beam and/or exclude the appearance of flare from the second surface.
Opto-TL produces windows from various crystals and glasses according to customer drawings:
- sapphire windows;
- germanium windows;
- silicon windows;
- windows from other materials.
The technologies for processing crystals and glasses developed in Opto-TL ensure high requirements for the purity, roughness and irregularity of the optical surfaces of windows, which allows them to be used in the state-of-art devices. In particular, sapphire laser windows can be used in systems with high radiation exposure. Windows made of germanium (3-5 microns and 8-14 microns) and silicon (3-5 microns) are used in spectroscopy, thermal imaging lenses, and infrared guidance systems.
