The 305 High Flatness Optical Glass Plate, also known as Model 305 high flatness glass, is an optical reference plate engineered to deliver ultra-high flatness and parallelism for precision inspection and calibration applications. The substrate is available in fused silica, alkali-free glass or borosilicate glass, and can be custom cut into strip, square or round formats to suit specific equipment requirements. With a Grade 305 ultra-high flatness standard, the plate exhibits minimal warpage and precise parallelism, providing a stable geometric baseline for high-precision vision systems and AOI calibration. The double-sided ultra-fine polished surfaces are free of scratches, pits, bubbles and stones, ensuring uniform light transmission without stray light interference for reliable optical measurement.

The 305 High Flatness Optical Glass Plate is designed for high-end precision inspection and calibration environments that demand an ultra-stable optical reference. It is widely used as a calibration reference plate for high-precision vision inspection systems, providing a verified flat surface that confirms the accuracy of cameras and measurement tools. In AOI automatic optical inspection equipment, the plate serves as a benchmark standard for verifying flatness and parallelism, helping to detect systematic errors in the inspection process. The material also works as an optical platform reference for laboratory instruments that require a clean, stable and low-thermal-expansion base. With options for custom strip, square and round cutting, the plate can be adapted to specific instrument geometries while maintaining the same Grade 305 flatness performance across all formats.
