Beijing Glass Research Institute Magnesium Fluoride-MgF2

We've started synthetic crystal research and growth since 1960. So far, we have developed over 30 types Synthetic Crystals

 

MgF2 crystal shows good optical and thermal-mechanical Properties. It is widely used for optical elements such as windows, lenses and prisms in the ultraviolet and infrared optical system where extreme durability is required. Its useful transmission range is 0.11μm-7.5μm. Because of its birefringence by optical anisotropy.MgF2 is also used as polarization optics.

Found in 1960,Beijing Glass Research Institute(BGRI) is a state owned institute pioneered in optical materials.Over 48 years, BGRI has been growing accompanied by contributing to domestic and international projects in diverse areas of science and industry. Continued focus on innovation won BGRI more than 140 awards. Many successful R&D projects are consecutively taken into production. R&D laboratories and business devisions of Synthetic Crystals, Optical Fibers, Special Glass, Optical Thin Films were established.Today we run complete facilities in a new plant, located in OIP industrial park, Beijing, enabling us to handle all research, development, fabrication and characterization in house on a better platform. We are now in the forefront of advanced optical material industry and specialized in: 1.SPECIAL OPTICAL FIBER AND DEVICES(PMF, PMC, Infrared fiber, cold light guide)2.COMMUNICATION OPTICAL FIBER;3.OPTICAL PROCESSING AND OPTICAL FILM( Optical elements polishing: Lens, prism, windows,IR windows; Optical coating service: AR, HR, PR, BBAR, IR, UV filter) 4.SYNTHETIC CRYSTAL(Fluoride Optical Crystal ;Fluoride Scintillation Crystal);5.SPECIAL GLASSES(Special glass used in steel industry )6.Temperature Component (I-type Optical Fiber Thermometric SensorThermistor;Film/Glass/Ceramic- Platinum Resistor;Beckman Thermometer (Differential Thermometer);Normal Thermometer)
