Quartz crystal has low strain birefringence, homogeneous refractive index, low thermal expansion coefficient and also excellent mechanical and chemical performance and piezoelectric property. Quartz crystal grid, window and prism are widely used in electro precision optics, laser, pressure sensor and particle processing system in biochemistry applications. Light guide are mainly used in aesthetic devices.
