## Overview

Alpha Nanotech's 4'' double-side polished fused silica/quartz wafer (JGS1 grade) offers ultra-smooth surfaces, precise 400 µm thickness, and exceptional UV transmittance, making it the go-to choice for advanced optical and research applications demanding stability and clarity.

## Description

We provide fused silica/quartz wafers (2 inches ~ 6 inches), and they are available in two grades, JGS1 and JGS2, respectively. Due to the low thermal expansion coefficient and high optical transmission, these quartz wafers have been widely used for optical-related and research-based applications. JGS1 grade contains a large number of hydroxyl groups (2000 ppm) and reaches a transmittance of 90% in the short-wave ultraviolet region. The JGS2 quartz glass produced by the hydrogen-oxygen flame is widely used for common applications that do not require a high transmission rate in the deep UV (DUV) region below 300 nm.
