Product Specifications

Technical details and manufacturing context for Lens Assembly

Definition
A critical component within Vision Systems that consists of multiple optical lens elements arranged in a specific configuration to control light transmission, focus images onto sensors, correct aberrations, and enable precise visual inspection, measurement, or recognition functions in industrial automation and quality control applications.
Working Principle
The lens assembly operates by refracting light through multiple optical elements with precisely calculated curvatures and arrangements. Each lens element bends light rays according to its refractive index and curvature, working collectively to focus light onto an image sensor, correct optical distortions, control magnification, and maintain image quality across the field of view.
