The W1124 N-BK7 Optical Glass Wafer from Sydor Optics is a precision-manufactured circular substrate designed for demanding optical and photonics applications. Fabricated from N-BK7 optical glass, a widely used borosilicate crown glass known for its excellent clarity and stable optical properties, this wafer delivers dependable transmission across the visible spectrum. With a 152.4 mm (6-inch) diameter and 1.935 mm thickness, it provides a lightweight yet durable platform for optical prototyping, system integration, and research environments where dimensional accuracy is important.

Engineered with tight optical specifications, the W1124 features a 95% central clear aperture, 20/10 cosmetic quality, and <25 arc-second parallelism, supporting precise optical alignment and consistent performance. Additional features include fine edge grinding, break-edge bevels for safer handling, and transmitted wavefront performance of <5 waves RMS over the clear aperture at a 632.8 nm metrology wavelength. These characteristics make it well-suited for laser systems, imaging setups, instrumentation, and optical research applications where reliable optical substrates are required.
