Classification of digital microscopes specialized in quality control and precision inspection in manufacturing. Targets microscope devices with built-in CCD/CMOS cameras capable of real-time observation, imaging, and measurement on PC monitors or tablet screens. Used for manufacturing quality control tasks including surface defect inspection of machined parts, metal structure observation, dimensional measurement, foreign matter analysis, and solder joint inspection. Unlike conventional optical microscopes, these feature standard digital image processing functions, measurement software, and USB/HDMI connectivity for easy recording, sharing, and analysis of inspection results. Includes handheld, stand-type, and inverted models for various applications, typically covering magnification ranges from 10x to 1000x.
