LT-PYRKAL is also an experienced producer of Hard and Soft Crystals, and possesses the appropriate research, production and control equipment to transform the grown crystals to Crystalline Optical Elements. The Company’s technicians are skilled in selecting and orienting crystals, cutting, lapping, polishing and coating them to perform up to laser standards. Two separate laboratories, equiped with X-Ray Orientation, Interferometer, Autocollimator and Spectrophotometers, are correspondingly dedicated to the treatment of Hard and Soft Crystals. Diamond turning capacity is available, while working with Sapphire, YAG, Quartz, Calcite, as well as with Fluorides -CaF2, BaF2, MgF2, LiF enables us to produce sizable Crystalline Optics, i.e. flats, prisms, lenses, windows and substrates.
