optical glass lens, quartzs glass plates ,quartz optical windows,

sio2 quartzs substrates, GS1,GS2 quartz cover lens

Characteristics and superiority

1, Shape:Round, square, rectangle;

2, Material : BK7, H-K9L ,UV fused silica,Corning7980, etc

3, Customer’s design and tailor made are welcome.

Big or small, the max size we did before was 2000mm; thick or thin, Thin or thick, from 1-400mm;

4, Dimension tolerance: +/-0.01 - +/-0.2mm( according to the requirement)

5,Future Processing: such as holes are available. Smallest hole is od0.5mm.

6, Surface quality :40/20 60/40 80/50

7, Transmittance >85%

8, Coating: high anti-UV film, antireflective film, gold, aluminum, silver series quartz glass

and quartz UV filters, curved reflector, filter glass and so on.

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.
