New Arrival｜Detailed Introduction to 16mm Focal Length F6.4A M12 Autofocus Liquid Lens

UltraOpto newly launches the 16mm Focal Length F6.4A M12 Autofocus Liquid Lens, a high-performance M12-mount imaging lens integrated with liquid autofocus technology. Designed specifically for high-end imaging scenarios requiring fast, precise, and mechanical-wear-free focusing, it combines high resolution, a large aperture, and a miniaturized structure, and can be widely used in industrial vision, intelligent security, medical testing, automation equipment and other fields.

I. What is the 16mm F6.4A M12 Autofocus Liquid Lens?

This lens adopts a standard M12 threaded mount, with a fixed focal length of 16mm and an aperture of F6.4. It has a built-in electronically controlled liquid lens, which achieves millisecond-level autofocus by changing the liquid curvature through voltage. There are no mechanical moving parts throughout the process, resulting in faster focusing, longer service life, and stronger shock resistance. It is an upgraded replacement for traditional fixed-focus and mechanical focusing lenses.

III. Working Principle of the Liquid Lens

The liquid lens encapsulates optically transparent liquid inside. By applying a weak voltage to change the surface curvature of the liquid, it adjusts the focal length and focusing position in real time, achieving:

Extremely fast focusing (millisecond-level)

Unlimited focusing cycles without mechanical wear

Shock and impact resistance, suitable for harsh industrial environments

Low power consumption and silent operation

IV. Core Product Features

16mm Golden Focal Length

With a moderate field of view, it can not only capture complete scenes but also ensure clear long-distance targets, making it suitable for medium-distance monitoring, inspection, and recognition scenarios.

F6.4 Large Aperture Design

Increases light input and reduces noise, maintaining high-quality imaging in indoor, nighttime, and low-light environments.

Liquid Autofocus Technology

No manual rotation for focusing is required; it supports electronically controlled real-time focusing, adapting to multi-distance and high-speed dynamic detection scenarios.

High Resolution and Low Distortion

The optical structure has undergone precise design and simulation optimization, with balanced image quality between the center and edges and extremely low distortion, meeting the requirements of high-precision measurement and recognition.

Standard M12 Mount

Highly versatile, it can directly replace traditional M12 fixed-focus lenses, enabling rapid upgrade to an autofocus system and reducing transformation costs.

Industrial-grade Stability and Reliability

No mechanical structure, resistant to vibration, high and low temperatures, and capable of 24/7 continuous stable operation, suitable for long-term operation scenarios such as production lines, transportation, and outdoor environments.

V. Typical Application Scenarios

Industrial Machine Vision: 

Production line defect detection, dimensional measurement, barcode/QR code reading, material positioning, robotic arm guidance
