photolithography reticle

Concentric circle transmission reticles are a special type of transmission-type optical calibration element. They use a highly transparent substrate to support concentric ring patterns, allowing the calibration pattern to be superimposed onto the image. They can also function as spatial filters to ...

A horizontal transmission micrometer reticle is a high-precision accessory designed specifically for optical measurement. It typically uses high-quality optical glass (such as Schott glass or quartz glass) as a substrate, and employs ultra-precision photolithography or vacuum coating technology to ...

A protractor reticle is a high-precision optical measuring component that combines angle measurement with optical reticle technology. It is typically made of high-purity optical glass, quartz, or a transparent polymer film, with precise angles, lines, or grid patterns etched onto its surface using ...
