Description
Product Introductions:
Quartz glass can transmit far ultraviolet, transmit visible light and near infrared optical curve.
It is characterized by small heat expansion factor, stable chemical capacity. Bubble, stripe and double refraction are better than common optical glass.
Quarts glass is necessary optical glass to stable optical factor in bad condition. Mainly apply in military, laser, metallurgical, optical instrument and stage light etc. high temperature window.
