121nm Magnesium Fluoride (121nm Mgf2)

121nm Magnesium Fluoride

121NM magnesium fluoride crystal, also known as extreme ultraviolet magnesium fluoride, performs atmosphere control during the crystal growth process to obtain high transmittance, and because of the complexity of the photoion welding process, there are requirements for crystal orientation, microstructure, lens processing and annealing requirements. It has the characteristics of high purity, high density, low impurity, etc. It can be processed in round, rectangular, open hole, meniscus, wedge Angle, flat convex, flat concave, double convex, double concave, open ball, prism.
