Fused quartz is one of the most popular & used glass substrates because of its low cost, high transmissivity & mechanical & thermal strength

Our OCTO high-purity fused quartz/ fused silica substrates/wafers (SiO2>= 99%%, type JGS2) are available in various thicknesses. Thanks to a large and live inventory, we can ship fast so you can start your project right away.

In case you require another dimension or if you are looking for a higher volume quote, please contact us.

Description

Fused quartz is one of the most used glass substrates because of its low cost, high electric isolation, high light transmittance (>85%-95% depending on the spectrum), chemical resistance, hardness, mechanical & thermal strength.

Our substrates/wafers are made of high purity fused silica (SiO2> =99%) are type JGS2 and feature the following specifications:
