AMO Scientific JGS2 Fused Silica Wafer and Substrate

AMO Scientific JGS2 fused silica wafers and substrates are high-purity SiO₂ optical substrates designed for semiconductor, photonics, MEMS, thin-film deposition and optical applications. Standard double-side polished (DSP) sizes include 1 inch, 2 inch and 4 inch / 100 mm wafers, as well as 10 × 10 mm substrates. Custom fused silica wafer dimensions, thicknesses and grades are also available.

JGS2 Glass is a high-purity synthetic quartz glass widely used in optics, semiconductors, and photonics. JGS2 has excellent transmission in the visible and near-infrared regions, but lower deep-UV transmission than JGS1.

Grade Spectral Transmission Range Typical Applications
JGS1 UV–Visible–IR (185–2500 nm) Precision optics, lithography
JGS2 UV–Visible (220–2500 nm) Optical windows, semiconductor processing
JGS3 Visible–IR (260–3500 nm) Infrared optics
