This precision wafer-style plate of Corning 7980 fused silica (Grade 5G) measures 126.62 mm square with a nominal thickness of 0.50 mm, and is engineered for applications requiring ultra-thin, optically pristine substrates. Supplied by Sydor Optics in Rochester, NY, this component is ideal for high-accuracy optics, micro-optical assemblies, imaging sensors, and instrumentation where minimal thickness meets tight tolerancing.
