BGRI Crystal Material Company Ltd. transformed from the Crystal
Laboratory of Beijing Glass Research Institute in 2000. We have
engaged in the growth, research and development of crystals for more
than 40 years.Take the optical crystal and the scintillation crystal
as key points, and most of them are halogenide material. Now we have
vacuum Bridgman furnace, atmospheric Bridgman furnace as many as 40
sets.The growth ability of fluoride crystals amounts to above 6 tons
per year.

The main products are as follows:
1$B!"(BCalcium fluoride (CaF2) crystal: The calcium fluoride single
crystal's most large diameter is 300mm; The greatest length is
200mm.Develops the ultraviolet level calcium fluoride single crystal.
Still had 90% transmission at 190nm.
2$B!"(BBarium fluoride (BaF2) crystal: The most large diameter is 160mm;
The greatest length is 350mm.
3$B!"(BMagnesium fluoride (MgF2) crystal: The most large diameter is 110mm;
The greatest length is 120mm.
4$B!"(BLithium fluoride (LiF) crystal: The most large diameter reaches is
170mm; The greatest length is 100mm.
5$B!"(BCerium flouride ceric fluoride (CeF3) crystal: The most large
diameter is 50mm; The greatest length is 200mm.
6$B!"(BLead fluoride (PbF2) crystal: The most large diameter is 50mm; The
greatest length is 60mm.

Our company can produce and provide the above mentioned fluorides
crystals with each kind of specifications and shapes according to the
user's needs.Our company can also provide each kind of oriented single
crystal and the orientde processing service,for example, Calcium
fluoride, lithium fluoride, magnesium fluoride and barium fluoride
crystal(111)direction,(100)direction and(101)direction as well as
other direction oriented cutting and polishing.
