fused quartz silica glass

1. rich experience for fused quartz silica glass 2. the low price 3. no bubble 3. good surface quality

We specialize in fused quartz silica glass.

1.Quartz silica glass can transmit far ultraviolet, transmit visible light and near infrared optical curve.

2.It is characterized by small heat expansion factor, stable chemical capacity.

3.Bubble, stripe and double refraction are better than common optical glass.

4.Quartz silica glass is necessary optical glass to stable optical factor in bad condition.

5.Mainly apply in military, laser, metallurgical, optical instrument and stage light etc. high temperature window.

We are the direct manufacturer. We can supply quartz silica glass.
