Magnesium Fluoride Lenses

Posted by Ningliu on May 5th, 2017

CVD magnesium fluoride (MgF2-CVD) has good mechanical properties, chemical stability, impact resistance, great anti thermal fluctuations and radiation. While it has excellent transmission from 0.11 to 9 um, suitable for optical lenses, wedge, and window manufacturing. MgF2 is also considered as durable material in deep UV and LWIR applications.
