Wedged windows
 |
Crystaltechno Ltd. manufactures optical wedged windows (wedges) from different types of optical crystals, glasses and Fused Silica.
Plane wedged windows (wedges) are used as transfer beam splitting or beam deviation optics. Standard wedge are made from glass BK7 and Fused Silica, but it's also possible to order from optical crystals CaF2 (Calcium Fluoride), BaF2 (Barium Fluoride), MgF2 (Magnesium Fluoride), Si (silicon), Ge (germanium), GaAs, Zinc Selenide (ZnSe) CVD.
