The W1039 N-BK7 Optical Glass Wafer from Sydor Optics is a precision-manufactured circular substrate designed for demanding optical and photonics applications. Made from N-BK7 optical glass, a widely used borosilicate crown glass known for its excellent optical clarity and stable refractive properties, this wafer delivers dependable transmission across the visible spectrum. With a 152.4 mm (6-inch) diameter and 3.175 mm thickness, it provides a lightweight yet durable platform for optical fabrication, system prototyping, and integration into advanced optical assemblies.

Engineered with tight optical specifications, the W1039 features a 95% clear aperture, <5 arc-second parallelism, and 20/10 cosmetic quality to support precise alignment and high optical performance. Additional characteristics include fine-ground edges, safety bevels, and transmitted wavefront performance of <2 waves at a 632 nm metrology wavelength, helping ensure consistent optical results and safe handling. These specifications make the wafer well-suited for laser systems, imaging equipment, instrumentation, and optical research environments where dimensional accuracy and optical quality are essential.
