Single Synthetic Optical Crystal Quartz is grown by hydrothermal method in autoclaves. It has trigonal crystal structure with right-handed or left-handed modification. Quartz crystals have low stress birefringence and high refractive index homogeneity. The optical transmission range of crystal quartz is 0.15-4 microns. Due to its piezoelectric properties, low thermal expansion, good mechanical parameters and excellent optical characteristics, cultured quartz is used in electronics, precision and laser optics, optical fibre communications, X-ray optics, and pressure sensors, ect.. |
