AFT-MCT-SR series high-precision grid ceramic calibration board
AFT-MCT-SR series of high-precision grid ceramic calibration plates adopt a ceramic-based standard plate which has the characteristics of small thermal expansion coefficient, high strength, high hardness, good abrasion resistance, low thermal conductivity, and good resistance to acid and alkali. The surface diffuse reflection treatment solves the problem of reflection of the glass material calibration plate under the condition of front light source in the application process, and can better identify the details of the calibration plate pattern to achieve higher calibration accuracy and measurement accuracy. It is a special high-precision calibration tool developed for universities, research institutes and machine vision integrators. The calibration software can easily obtain the calibration data of the camera.
