The W1074 S-BSL7 Optical Glass Wafer from Sydor Optics is a precision-manufactured circular substrate designed for demanding optical and photonics applications. Fabricated from Ohara S-BSL7 optical glass, this wafer offers stable refractive properties and excellent transmission characteristics across the visible spectrum. With a 300 mm diameter and 5.97 mm thickness, it provides a large, robust platform for optical system integration, prototyping, and advanced research environments.

Engineered for high-quality optical performance, the W1074 features fine edge grinding, a 40/20 cosmetic specification, and <3 arc-second parallelism over a 1-inch area to support precise optical alignment. Additional specifications include a 95% central clear aperture, 1/10 wave RMS transmitted and reflective wavefront performance, and precision bevels for safe handling and installation. These characteristics make it well suited for laser research, semiconductor processing, industrial instrumentation, and other advanced optical systems where dimensional accuracy and optical consistency are critical.
