The W1105 N-BK7 Grade A Fine Annealed 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 valued for its excellent optical clarity, stable refractive index, and strong transmission across the visible spectrum, this component provides reliable performance in precision optical systems. The wafer measures 203 mm in diameter with a 6 mm thickness, offering a robust and dimensionally stable platform for optical fabrication, prototyping, and integration into advanced optical assemblies.

Engineered with tight optical specifications, the W1105 features Grade A fine annealing, 40/20 cosmetic quality, and ≤1 arc-minute parallelism to support accurate alignment and consistent optical performance. Additional characteristics include a 182.7 mm central clear aperture, ≤0.5 waves PV reflective wavefront over the clear aperture, fine edge grinding, and precision bevels for safer handling and installation. These features make the W1105 well-suited for applications such as laser systems, imaging equipment, instrumentation, and optical research environments where high optical quality and dimensional precision are essential.
