MgF2 Crystals

We can supply magnesium fluoride (MgF2) crystals upon your request. MgF2 single crystals have a very broad transmission spectrum from deep ultraviolet (DUV) to long wavelength infrared (LWIR). MgF2 crystals are highly resistant to thermal and mechanical shock and optical radiation, and are chemically stable.

Features And Benefits

1. Wide transparent spectrum: 0.11～7.5μm 2. Chemically stable. 3. High mechanical and thermal shock resistance

Application

MgF2 crystal has become the most suitable material for 193nm ArF and 248nm KrF excimer lasers due to its excellent DUV transmission properties. MgF2 has great birefringence, making it suitable for making waveplates. MgF2 crystals can be used in MWIR and LWIR thermal imaging applications, as well as in thin film growth.
