Description

Magnesium fluoride (MgF2)crystal has wide light transmission range and good light transmission performance in the wavelength range of 0.12 μ m ~ 7.5 μ m. With high single crystal rate and harder material than CAF2, it is mainly used in ultraviolet band. It is an ideal material for making various optical elements, such as windows, lenses, prisms and cylindrical lenses. It can be used in wave plate, laser system, coated crystal, vacuum window, PBS light source, microscope, optical instrument, etc.
