The W1206 N-BK7 Optical Glass Window from Sydor Optics is a precision-manufactured square substrate designed for high-performance optical systems. Fabricated from N-BK7 optical glass, a widely used crown glass known for its excellent transmission, low dispersion, and optical homogeneity, this component delivers dependable clarity across the visible spectrum. The window measures 180 mm x 180 mm with a 6.35 mm thickness, providing a stable and durable platform for integration into demanding optical assemblies and research environments.

Engineered with tight optical tolerances, the W1206 features ≥90% clear aperture, 40/20 cosmetic quality, fine edge grinding, and precision bevels to support reliable performance and safe handling. Additional specifications such as ≤2 µm parallelism and reflective wavefront control help maintain consistent optical alignment in precision systems. These characteristics make the W1206 well-suited for applications including laser windows, instrument and viewing windows, sensor protection, debris shields, and vacuum windows, where optical quality and durability are critical.
