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.
