UltraOpto’s M12Li16-F6.4B Autofocus Liquid Lens is a compact, high-precision autofocus optical solution tailored for 1/1.8” sensors, designed for industrial machine vision, automated inspection, and precision imaging applications. With ultra-low distortion, a flexible working distance range, and a compact Φ10 mount, it delivers consistent, high-quality performance in space-constrained industrial environments.
Core Optical Performance
This lens features a 16mm nominal focal length (adjustable 13.76–17.16mm with the integrated liquid lens) and a fixed F6.4 aperture (F6.9–F7.0 with liquid lens engaged), supporting a versatile working distance range of 60mm–8m. At the reference wavelength of 570nm, it achieves an industry-leading 0.2% maximum distortion, ensuring pixel-perfect accuracy for dimensional measurement, defect detection, and high-detail imaging tasks.
6MP high resolution: Delivers sharp, crisp imagery ideal for quality control and robotics guidance.
78% relative illumination: Minimizes vignetting across the Φ9.2mm image circle, ensuring uniform brightness from center to edge.
Broad wavelength compatibility: 435–680nm working wavelength range supports visible-light imaging for diverse industrial workflows.
Compact, Precision-Engineered Design
Built with a total track length (TTL) of only 20.75mm and a compact Φ10 mount, this lens integrates seamlessly into ultra-compact vision systems, embedded devices, and portable imaging setups.
15° maximum chief ray angle (CRA): Ensures compatibility with a wide range of 1/1.8” sensors, optimizing light delivery for consistent performance.
3.83mm back focal length (BFL): (including 0.55mm CG) allows flexible integration with various sensor modules, simplifying system design.
Compact footprint: Ideal for space-constrained applications like handheld scanners, robotics end-effectors, and miniaturized inspection systems.
Industrial-Grade Durability & Reliability
Engineered for continuous operation in harsh environments, the lens offers robust temperature resilience:
Operating temperature: -20°C to +70°C
Storage temperature: -40°C to +85°C
The integrated liquid lens enables fast, maintenance-free autofocus without moving mechanical parts, reducing wear and downtime in high-cycle applications. This makes it ideal for 24/7 industrial operations, including logistics scanning, factory automation, and scientific imaging.
