Optical flats are standard plane gauges for high-precision metrology, precision-manufactured from highly homogeneous optical glass or quartz. They verify gauge-block wringing and flatness, and flatness of instrument measuring and working faces. They also serve as standards for precision flat parts such as optics, platforms, plates, and guideways, providing reference planes and templates for metrology organizations and laboratories. The series offers accuracy grades1 and2 across common dimensions, with high surface finish and low flatness error for different calibration grades.

Applications

Metrology verification organizations: flatness verification of gauge blocks, straightedges, surface plates and guideways. Industrial laboratories: flatness inspection of precision mechanical parts, optical parts and high-grade platforms. Production quality control: flatness inspection of machine-tool guideways, tables, seals and other workpieces. Research and teaching: standard flat reference plates for optical experiments and metrology instruction.

Key Features

Precise flatness: grade 1/2 standards and minimal errors ensure reliable metrology. Excellent homogeneity: few impurities, no bubbles/striae and good thermal stability minimize long-term flatness changes. Precision-polished surfaces without scratches/pits suit direct wringing tests. Mainstream sizes 36×36mm to 200×200mm cover diverse ranges. Grade 1 serves precision verification; grade 2 serves routine cost-effective metrology. Yasi Optical advantages: quality optical glass/quartz preserves flatness; precise figure control meets grade 1/2 standards for reliable results; mainstream stock enables rapid response; custom sizes/grades suit nonstandard uses; every flat inspected for flatness and surface finish.
