Quartz crystal is grown by hydrothermal-synthesis method in autoclaves. It has trigonal crystal structure with right-handed or left-handed modification. Quartz has low stress birefringence and high refractive index homogeneity . The optical transmission range of crystal quartz is 0.15-4um. Due to its piezoelectric properties, low thermal expansion , good mechanical parameters and excellent optical characteristics, quartz is used in electronics , precision and laser optics, optical fibre communications, X-ray optics, etc. Our quartz crystal main products are as follows:
