Crystals Birefringent Crystals MgF2


Magnesium Fluoride (MgF2 crystals)is used for optical elements where extreme ruggedness and durability is required. Its useful transmission range is 0.12 μm - 8.5 μm. Irradiation does not lead to color centers. It is a rugged, hard material which is resistant to thermal and mechanical shock and can be worked to the highest standards. MgF2 crystal is slightly birefringent and usually supplied with the optic axis cut perpendicular to the window faces.

Magnesium Fluoride (MgF2 crystals)has the following exceptional properties that make it a very important optics crystal:

(1) High optical transmittance from the vacuum ultraviolet to the infrared spectrum region(0.12~8.5μm).
(2) Resistant to mechanical and thermal shock, to radiation.
(3) Chemically stable.
(4) Used for Optical prisms, lenses, wedges, windows, other optical components,and etc.
(5) A positive birefringent crystal ,used for optical fiber communication.

CLASER's MgF2 crystals are high transmittance in DUV for large size single domain, and especially suitable for Excimer or DUV windows.

MgF2 crystals: High transmittance

5% @ 120nm, 78% @ 140nm, 90% @ 200nm,93% @ 300-5000nm.

We can produce UV Blank, UV Windows, UV Lenses, UV Cylindrical Lenses, UV Prisms, UV Wedges and etc. according to custmers' requirments.
