Qinhuangdao Inrinsic Crystal Technology Co., Ltd Optics & Coatings windows are made from select grades of the finest available optical materials. VUV/UV windows are suitable for a large range of VUV-UV applications. Flat laser windows are suitable for high-power laser applications and as substrates for mirrors and beamsplitters.
MgF2 (Magnesium Fluoride) is positive uniaxial crystal with a very high optical transmittance from the vacuum UV to IR. It also has a large resistance to mechanical and thermal shock, to optical radiation, and is chemically stable, making it a very useful materials for UV and IR optics.  
we also can offers a-cut (or [100] cut) MgF2 crystals for the maximum birefringence.  c-cut (or cut along the optical axis) with minimum birefringence, or random-cut (cut along a random axis)  MgF2 windows are also available.
Note: Excimer-grade CaF2 and MgF2 substrates are available for laser cavity optics and are available with transmittance traces for an additional charge.
