16mm focal length M12 Autofocus Liquid Lens


UltraOpto’s 16mm focal length M12 Autofocus Liquid Lens is a high-performance industrial autofocus lens designed for 2/3" sensors, delivering ultra-low distortion and consistent imaging for precision industrial machine vision applications.


Core Optical Specifications

This lens features a 16mm nominal focal length (adjustable 15.0–17.0mm with the integrated liquid lens) and a bright F4.3 aperture, maintaining reliable light transmission across its 100mm–1m working distance range. At the reference wavelength of 570nm, it achieves an industry-leading 0.5% max distortion, ensuring pixel-perfect accuracy for inspection, metrology, and quality control tasks. The lens supports 6MP resolution and offers 84% relative illumination, minimizing vignetting for uniform brightness across the entire Φ11.2mm image circle.


Compact, Precision-Engineered Design

Built with a total track length (TTL) of only 15.6mm and a standard Φ14 M12 mount, the lens integrates seamlessly into compact vision systems without sacrificing optical quality. Its 16° maximum chief ray angle (CRA) ensures compatibility with a wide range of 2/3" sensors, while the compact footprint makes it ideal for space-constrained automation setups. The back focal length (BFL) of 8.23mm (including 0.55mm CG) allows for flexible integration with various sensor modules.


Robust Performance for Demanding Industrial Environments

Designed for continuous operation in harsh conditions, the lens operates reliably across a temperature range of -20°C to +70°C (storage: -40°C to +85°C). The integrated liquid lens enables fast, maintenance-free autofocus without moving mechanical parts, enhancing durability and reducing downtime in high-cycle applications. With a working wavelength range of 435–680nm, it supports visible-light imaging for diverse industrial workflows, including robotics, logistics scanning, and scientific imaging.
