COE Optics can offer Magnesium Fluoride (MgF2) Windows with 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 (MgF2) Windows can work at 120nm wavelength with transmission >/=60% T. COE Optics can supply single-crystal Magnesium Fluoride (MgF2) Windows, which is much better compared with other companies polo crystal Magnesium Fluoride (MgF2) Windows.
COE Optics can supply MgF2 windows with C-axis orientation with accuracy +/-1 degree, to minimize birefringence. MgF2 material has a Knoop Hardness of 415 and an index of refraction of 1.38. MgF2 is a rugged material resistant to chemical etching, laser damage, and mechanical and thermal shock.
• Good transmission from 120nm to 8000nm
• Very Durable
• Resistant to Chemical Etching
• Resistant to thermal and mechanical shock
• High Laser damage threshold
