BGRI Crystal Material Company Ltd. transfered 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、Calcium 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、Barium fluoride (BaF2) crystal: The most large diameter is 160mm; The greatest length is 350mm.
3、Magnesium fluoride (MgF2) crystal: The most large diameter is 110mm; The greatest length is 120mm.
4、Lithium fluoride (LiF) crystal: The most large diameter reaches is 170mm; The greatest length is 100mm.
5、Cerium flouride ceric fluoride (CeF3) crystal: The most large diameter is 50mm; The greatest length is 200mm.
6、Lead 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.
