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 features high precision,high stability,high contrast and excellent environmental resistance,and is widely used in visual inspection,dimensional measurement,motion control,precision

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 optical performance. It is widely used in industries such as photography, medical imaging, robotics, and 3D scanning. The USAF 1951 Resolution Calibration Board is perfect for

Black Background White Dot Calibration Board / Photolithography White Film The photolithography white film dot array calibration plate is made using semiconductor level photolithography exposure and development technology, with high stability optical grade PET/PC white film as the core substrate. The surface is formed with high-precision white dot array and directional positioning marks by photolithography, which solves the problem of traditional glass calibration plates

High Precision Resolution Board (USAF1951 Positive/Negative Film) 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 system performance optimization, new imaging scheme verification), multi camera/multi-channel system consistency

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 measurement and control systems,widely used in equipment requiring accurate position feedback,such as CNC machine tools,robots,servo systems,automation equipment,etc. 1.
