Alkor Technologies: Custom Optical Components from VUV to Far IR
Alkor Technologies is a Russian manufacturer of precision optical components with over 35 years of production experience in Saint Petersburg. We manufacture windows, lenses, prisms, beamsplitters, ATR elements, mirrors and interference filters from more than 20 optical materials — from fused silica and optical glass to germanium, ZnSe, KBr and LiF — across the full spectral range from 105 nm (VUV) to 25 µm (far IR). ISO 9001:2015 certified. MIL and GOST quality standards available. Custom quote within 24 hours.
Materials: 20+ Optical Materials on One Production Site
We work with all major UV, VIS and IR optical materials. Material selection is guided by the required spectral range, mechanical load, chemical environment and operating temperature:
Optical Crystals: Potassium Bromide - KBr, Sodium Chloride - NaCl, Potassium Chloride - KCl, Cesium Iodide - CsI, Calcium Fluoride - CaF2, Barium Fluoride - BaF2, Lithium Fluoride - LiF, Magnesium Fluoride - MgF2, Zinc Selenide - ZnSe, Sapphire - Al2O3, Silicon and Germanium optical grade crystals;
Scintillation Crystals: NaI(Tl), CsI(Tl), BaF2;
Sillenite Photorefractive crystals: BSO and BGO;
Glasses: Optical glasses, UV and IR grade Fused Silica.
Most of our work tends to be bespoke — the wide range of materials and applications in the IR, UV and visible regions of the spectrum means standard catalog items rarely meet every requirement. We design and manufacture to your drawing, or reverse-engineer from a sample or a competitor catalog reference number.
