The W1085 SCHOTT N-BK7 Grade A Fine Annealed optical glass window from Sydor Optics is a precision-manufactured square substrate designed for demanding optical and photonics applications. Made from SCHOTT N-BK7 optical glass, a widely used crown glass known for its high transmission, low dispersion, and excellent optical homogeneity, this component provides reliable clarity and stable performance across the visible spectrum. The window measures 63.5 mm x 63.5 mm with a 3.0 mm thickness, making it well suited for optical assemblies, prototyping, and laboratory instrumentation where consistent optical quality is required.

Engineered with tight optical specifications, the W1085 features fine edge grinding, a 40/20 cosmetic specification, and <30 arc-second parallelism to support precise alignment within optical systems. Additional features include a 90% clear aperture, 1/4 wave per inch reflective wavefront, and precision bevels for safer handling and integration. These characteristics make it a dependable choice for applications such as laser systems, imaging equipment, sensor protection windows, and research instrumentation where dimensional accuracy and optical consistency are essential.
