Auto-Focus System (AF), an auto-focus tracking system utilizes sensors or lens assemblies to automatically adjust focal points for enhanced image clarity. Serving as the "eyes" of machine vision and precision measurement, it performs defocus detection and compensation within milliseconds to ensure optimal imaging plane alignment. The core functionality lies in rapidly identifying and locking onto the target object's focal position through various technical means. Optical auto-focus systems convert "defocus errors" into "micro-nano scale displacement commands," enabling microscopes, AOI equipment, and laser processing systems to maintain sub-micron clarity even in high-speed, large-depth-of-field, and complex surface scenarios. As a fundamental capability driving higher yields in semiconductor and advanced manufacturing, these systems are widely deployed in photography, microscopic imaging, industrial inspection, and related fields.
