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 ...

The USAF 1951 Resolution Test Card (Resolution Board) is a classic standardized testing tool based on USAF standards, widely used in imaging system spatial resolution testing, machine vision inspection system evaluation, optical system development and optimization (lens design verification, optical ...

A crosshair reticle, also known as a crosshair reticle, is a high-precision optical element. It uses high-quality optical glass as a substrate and employs ultra-precision photolithography or vacuum coating technology to etch lines containing a cross and specific branching patterns onto its surface. ...

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 crosshair micrometer (typically used as part of a transmission reticle or stage/eyepiece micrometer) is a high-precision optical measurement standard. It uses high-quality optical glass as a substrate, with clear crosshairs and micron-level graduations etched onto its surface using ultra-precision ...

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 ...

Glass Code Plate Glass code disc is the core component for signal transmission in photoelectric encoders,usually made of transparent glass material with a series of engraved lines or optical patterns formed on its surface through precision processing.It is an important element in modern precision ...

High Precision Glass Line Ruler High-precision glass line ruler is an optical precision measuring element that uses high-stability optical glass as the substrate and forms precise line patterns on the glass surface through high-precision photolithography,coating,etching and other processes.It ...

High-Precision Resolution Board The USAF 1951 Resolution Calibration Board is a standard tool used for camera resolution testing and optical system calibration. Featuring a set of progressively finer line pairs, this calibration board is designed to assess lens resolution, image sharpness, and ...
