Optical surface defect inspection equipment is a specialized device that automatically detects defects such as scratches, stains, foreign matter, color unevenness, and printing defects on product surfaces in manufacturing lines using optical technology. Combining CCD cameras, laser light sources, and image processing systems, it performs high-speed non-contact inspection of surface quality for metal processed products, resin molded products, films, glass, semiconductor wafers, LCD panels, and other materials. As an inline inspection system integrated into production lines, it enables automatic rejection of defective products and quality data collection, making it essential equipment for quality control automation in manufacturing processes of automotive parts, electronic components, and packaging materials. Unlike dimensional or shape measurement, it is positioned as optical measurement equipment specialized in visual defect detection on surfaces.
