Product overview

Magnesium Fluoride crystal is used as a lens, prism and window for wavelength from 110nm to 7.5μm. It is a most suitable material as window for ArF Excimer Laser, for the reason of its good transmission at 193nm. It is also effective as an, optical polarizing element in the ultraviolet region. Any more MgF2 crystal has fine grain, which is appropriate as a vacuum evaporation coating materials.

Scitlion is able to offer
Various optics for IR & VUV application, using our MgF2 crystal materials
MgF2 VUV Windows for ArF Excimer Laser
Good quality MgF2 crystal blank materials
OEM service for good quality MgF2 crystals
Orientation:<001>、<100>、<110>、<210>、<111>
