Annual Sale increment of BCT

BCT designs, develops and manufactures a wide variety of crystals, including laser crystals, nonlinear optical crystals, photorefractive crystals, electro-optical crystals, optical crystals ranging from IR to UV, piezoelectric crystals and scintillating crystals, etc.

There are 5 professional factories, Quartz Crystal Plant, Laser and NLO Crystal Plant, Optical Crystal Plant, Transparent Ceramic Plant and Crystals Processing Plant, in BCT developing different kinds of crystal technologies.

Quartz Crystal Plant is mainly engaging in hydrothermally grown crystals.

Large size single crystal quartz has been developed into world renowned quality material.

Laser and NLO Crystal Plant is fostering crystals by using Top Seeded Solution Growth (TSSG) from self-flux and Czocharalski method. Single KTP crystal is famous for high utilization per cent in PPKTP applications all over the world.

Optical Crystal Plant is growing crystals ranging from infrared to ultraviolet in Bridgman stockbarger way. It is a leading manufacturer of High-grade Ultraviolet fluoride especially MgF2 single crystal and CaF2 single crystal in China.

Transparent Ceramic Plant is developing polycrystals in the means of advanced ceramic technology. It is the unique Chinese producer of transparent spinel that has reached world level, and has good future to substitute sapphire in both large size and low cost applications.

Crystals Processing Plant house its cutting and polishing machinery, X-ray and ZYGO measurement systems, clean room and optical workshop, integrated to promote and offer clients and OEMs related crystals products that meet customers’ needs.
