The W1122 Ohara S-BSL7 Grade A Fine Annealed optical glass blank from Sydor Optics is a precision-manufactured square substrate designed for high-performance optical applications. Made from Ohara S-BSL7 optical glass, this component provides consistent refractive properties and strong transmission characteristics, making it well suited for demanding optical systems and fabrication processes. The blank measures 127 mm x 127 mm with a 2.8 mm thickness, offering a lightweight yet stable platform for prototyping, optical assemblies, or custom fabrication.

Engineered with tight dimensional tolerances and high-quality finishing, the W1122 features fine edge grinding, a 60/40 cosmetic specification, and a reflective wavefront specification of <1 wave PV at a 632.8 nm metrology wavelength. Additional specifications such as <30 arc-second parallelism, a 114 mm x 114 mm clear aperture, and precision bevels support reliable integration into optical systems. These characteristics make it an excellent choice for applications in laser systems, instrumentation, imaging equipment, and research environments where optical quality and consistency are essential.
