1. Overview

Machine vision lenses are optical components designed to capture precise visual data for automated inspection and analysis systems. These lenses interface with industrial cameras to enable high-accuracy imaging in applications ranging from quality control to robotic guidance. Their importance stems from their ability to enhance production efficiency, reduce human error, and enable real-time decision-making in smart manufacturing environments.
