The W1038 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 optical clarity and stable refractive properties, this wafer provides reliable transmission across the visible spectrum. Measuring 152.4 mm in diameter with a 4.075 mm thickness, it offers a durable and dimensionally stable platform for optical fabrication, prototyping, and system integration.

Engineered with tight optical specifications, the W1038 features 95% clear aperture, <5 arc-second parallelism, and a 20/10 cosmetic quality, supporting precise alignment and high optical performance. Additional characteristics include fine-ground edges, a 0.2 mm precision bevel, and transmitted wavefront performance of <2 waves over the clear aperture at a 632 nm metrology wavelength. These specifications make the wafer well-suited for laser systems, imaging equipment, instrumentation, and optical research applications where consistent optical quality and dimensional accuracy are essential.
