▶Utilizes high-precision direct-write photolithography technology to achieve nanoscale pattern processing, perfectly meeting the demands of high-density, high-resolution micro/nanostructure precision manufacturing.
▶Up to 90% light transmittance enhances image clarity and contrast, improving measurement accuracy and stability.
▶±5um accuracy with strict process control; each calibration plate meets specifications, reliable for scientific research and industrial testing.
▶High flatness is achieved through uniform chrome plating, which reduces the impact of surface geometric deviations on camera calibration; flatness improves calibration accuracy and stability.
▶Suitable for resolution testing, calibration and QC of optical devices (cameras, microscopes, telescopes); also for performance evaluation of image sensors, film and photos.
