UV and IR Optics
Substrates and finished optical components such as windows, lenses, mirrors manufactured from lithium fluoride (LiF), magnesium fluoride (MgF2), calcium fluoride (CaF2), barium fluoride (BaF2), sapphire (Al2O3), zinc selenide (ZnSe), germanium (Ge) for UV and IR applications.

Magnesium fluoride (MgF2) is a proven material for high energy lasers, and particularly for lasers operating in the UV range.

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.

Lithium fluoride (LiF) crystals are well-suited for manufacturing of optical elements (mirrors, windows, lenses) for UV, visible and 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.
 Lenses/bariumfluoridewindows(1).jpg)
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.
 Components/al2o3_img.jpg)
It is transparent from 150 nm up to 6 mm in the middle infrared. Sapphire exhibits anisotropy in many optical and physical properties.
 Lenses/zinc_sl_img.jpg)
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.

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 (windows, mirrors, lenses) for high power IR lasers.
 Mirrors/grafikas.jpg)
Cu metal mirrors are intended for the following typical applications: optical resonators in pulsed and CW high power IR lasers optical systems of transforming, transmitting and focusing of laser beams.
 Components/Ge_img.jpg)
Germanium (Ge) based optical components are widely used for IR applications. Germanium (Ge) is well suited for manufacturing of windows and lenses for IR applications in lasers and optical systems.
 Mirrors/grafikas(1).jpg)
Coated silicon substrates are commonly used as mirrors for CO2 lasers. Its advantages are good durability, thermal stability and relatively low cost. The total reflectors are used as rear reflectors and fold mirrors and externally as beam benders
