The W1094 Fused Silica Wafer (Corning 7980, Grade 0G – 150mm dia. x 1mm thick) is a high-purity optical substrate designed for demanding applications where precision, uniformity, and optical performance are critical. Manufactured from Corning 7980 fused silica, this material is known for its exceptional homogeneity, low birefringence, and excellent transmission properties, making it ideal for use in photolithography, laser systems, and advanced optical research. With a large 150mm diameter and tightly controlled thickness tolerance, it provides a stable and consistent platform for both development and production environments.

Engineered with Sydor’s precision fabrication capabilities, the W1094 wafer features a fine ground edge, 60/40 cosmetic quality, and a generous clear aperture to support high-performance optical applications. Its semi-flat geometry and controlled transmitted wavefront ensure reliable optical consistency across the surface, making it well-suited for metrology, inspection, and semiconductor processes. Whether used as a test wafer, optical window, or substrate, this fused silica component delivers the durability and performance required in today’s most advanced technical environments.
