Features of Magnesium Fluoride Lenses

One-stop customized production: Solar Valley can process a variety of infrared lenses, flat convex, double convex, convex and concave structure aspherical Magnesium fluoride Lenses.The shape can be round, D-type, square and so on.

Material: Magnesium fluoride is tetragonal crystal system, characterized by anisotropy. Therefore, single crystals are considered in precision imaging and signal transmission. Magnesium fluoride (MgF2) is an excellent infrared optical material with a transmittance range of 0.12-10um, which is not easy to be chaotized, and a refractive index of about 1.38, which is a very excellent ultraviolet band material and the most important low-refractive index lens material.

Lens performance: CVD magnesium fluoride (MgF2-CVD) has good mechanical properties, chemical stability, impact resistance, heat wave resistance and radiation ability. Although it has excellent transmittance in the 0.11 to 9 um range, it is suitable for optical lens, wedge and window manufacturing. MgF2 is also considered to be a durable material in deep ultraviolet and long-wave infrared applications.
