PAM XIAMEN offers Magnesium Fluoride MgF2 Crystal.
Magnesium fluoride, MgF2, crystals have been widely used as windows, lenses, and prisms for wavelength from 110 nm to 7.5 um. It is the most suitable material for ArF excimer lasers used in pulsed laser deposition techniques. For its excellent ulta-violet transmittance at 193nm, it is effective as optical polarizing element.
PAM XIAMEN offers the following choices:
Customized crystal growth and machining
High quality MgF2 blank crystal materials in discs, plates, rods, customized for customers
High quality MgF2 VUV windows for ArF Excimer Laser
Customized MgF2 optics for IR and VUV applications
MgF2 viewport windows for Infrared thermography from 8 um to 14 um.
