Product Description
Product Overview
High-precision synthetic quartz fused silica wafers with double-side polishing, available in 4-inch diameter and 0.5mm thickness. These UV-grade JGS1 wafers offer exceptional optical clarity and transmission performance for demanding industrial applications.
Optical Grade Specifications
Our Ultraviolet Grade Fused Silica (JGS1) wafers provide high transparency in the ultraviolet spectral range with approximately 90% transmission in VIS and UV wavelengths. JGS2 wafers offer a more economical alternative with transmission starting below approximately 270 nm, while Full Spectrum Fused Silica (JGS3) wafers feature very low OH-content (
