DM Optical Auto-focus FA Lens Series
Designed for automated factory environments, the DM Optical Auto-focus FA Lens Series delivers sharp imaging across an 8–50mm focal length range. Optimized for 2/3″ and 1.1″ sensors (up to 65MP), it features precision auto-focus accurate to ±0.001° with sub-millisecond response times. Supporting RS232 and pulse control, it integrates into machine vision systems for alignment, measurement, and surface inspection. Low distortion and high contrast across the focal range ensure geometric fidelity for demanding metrology and defect detection.
