The W1222 S-BSL7 Optical Glass Wafer from Sydor Optics is a precision-manufactured circular substrate designed for high-performance optical and photonics applications. Produced from Ohara S-BSL7 optical glass, this wafer provides stable refractive properties and reliable optical transmission across the visible spectrum. With a 12-inch (304.8 mm) diameter and 2.1-inch (53.34 mm) thickness, it offers a large, durable platform for optical fabrication, system integration, and advanced research environments where dimensional stability and optical consistency are critical.

Engineered with tight optical specifications, the W1222 features fine edge grinding, a 60/40 cosmetic quality, and <1 arc-minute parallelism, supporting precise optical alignment and reliable performance in demanding systems. Additional specifications include a 90% clear aperture, reflective wavefront performance of ≤1.5 waves PWR and ≤0.25 wave irregularity, and precision bevels for safer handling and installation. These characteristics make it well suited for laser research, metrology, semiconductor processing, and industrial instrumentation, where high-quality optical substrates are essential.
