Description

Description

Magnesium Fluoride (MgF2) is commonly used for UV windows, lenses and polarisers. It is also useful in its transmission range for some IR spectroscopy applications for wavelength from 110nm to 7.5 um. It also has a large resistance to mechanical and thermal shock. Magnesium Fluoride (MgF2) Windows offer excellent broadband transmission from the deep-UV to the mid-infrared. DUV transmission makes them ideal for use at the Hydrogen Lyman-alpha line and for UV radiation sources and receivers, as well as excimer laser applications. Magnesium Fluoride or MgF2 is grown by vacuum Stockbarger technique in ingots approximately 120mm in diameter

​

Features:

  • >50% Transmission at 120 nm
