Magnesium Fluoride Plano-Convex Lenses PMg03E004
The magnesium fluoride plano-convex lens has an optical transmittance of nearly 90% in the spectral range of 200-9500nm. Commonly used in low-temperature refrigeration imaging systems, aerospace optical systems, and laser optical systems, such as lenses, beam splitters, filters, prisms, and window lenses. This material has a certain degree of water solubility and is suitable for use in dry environments. UM OPTICS can provide a diameter of 2-300mm and a thickness of 0.12-60mm (accuracy can reach 20-10,1)/ 10L@633nm )Barium fluoride flat convex lenses can be coated with MgF2, UV-AR, UV-VIS, VIS-EXT, VIS-NIR, NIR I, NIR II, Telecom NIR, SWIR, SWIR, YAG-BBAR and other film systems.
