Substrates and finished optical components - windows, lenses and mirrors made from lithium fluoride (LiF), magnesium fluoride (MgF2), calcium fluoride (CaF2), barium fluoride (BaF2), sapphire (Al2O3), zinc selenide (ZnSe), copper (Cu), germanium (Ge) and silicon (Si) for laser and optical instruments applications in UV and IR wavelength ranges.
Low solubility and wide transmission range makes it useful for many applications, including: mirror substrate for UV laser systems; substrate for manufacturing windows, lenses for UV, IR applications.
The optical material used for cross-polarized wave (XPW) generation is Barium Fluoride (BaF2) crystal with z ([001]) or holographic ([011]) crystallographic orientation. We offer [011] orientation crystals for XPW generation.
Barium fluoride (BaF2) is used for optical windows, prisms and lenses transmitting from ultraviolet into infrared, it can be used as infrared laser window or lens.
BaF2 is recommended for use as a vacuum ultraviolet window where high radiation resistance is required. BaF2 is relatively more soluble than MgF2 and CaF2.
Zinc selenide (ZnSe) is the most popular material for infrared applications. Due to a very wide transmission range covering 0.6-22 µm chemical vapor deposition grown ZnSe as a high optical quality material is used to manufacture optical components.
