Low OH- hydroxyl  Quartz Tube
 With the change of the hydroxyl content in the Quartz Tube glass, the performance of the quartz glass also change. As the hydroxyl  content increases, the viscosity, density, refractive index of the quartz glass is reduced,  But infrared absorption, expansion coefficient increases.
