High Purity Synthetic Fused Silica: Suprasil® CG

Source: Heraeus Quartz America, LLC.

 	High Purity Synthetic Fused Silica: Suprasil

Suprasil ® CG is a high purity synthetic fused silica manufactured by flame hydrolysis, ideal for DUV to UV/VIS commercial grade optics. This silica features a low bubble and inclusion content, typical UV transmission of k200: 3,5 x 10-3/ cm, stress induced birefringence, a well-established production process, and much more.
