Product Details

Birefringent Crystal Quartz

Overview:

Single Synthetic 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 0.2-2.5microns. Due to its piezoelectric properties, low thermal expansion, good mechanical parameters and excellent optical characteristics, crystal quartz is widely used in electronics, precision and laser optics, fiber communications, X-ray optics, pressure sensors and etc.
