Quartz Crystal
Quartz crystal is grown by the hydrothermal method in an autoclave and has left-handed and right-handed forms. Quartz crystal has low stress birefringence and high refractive index uniformity, with a transmission range of 200-2500nm. Due to its piezoelectric properties, low thermal expansion coefficient and excellent mechanical and optical properties, quartz crystal is used in electronics, precision optics and laser technology, optical communication, X-ray optics and pressure sensors.
