UltraOpto is proud to introduce the16-F6.4A mm focal length M12 Autofocus Liquid Lens—a cutting-edge, high-precision optical solution engineered for 1/1.8" sensors, combining ultra-low distortion, flexible focus control, and robust industrial-grade performance. Tailored for machine vision, automated inspection, and precision imaging workflows, this lens redefines reliability in compact optical systems.
Core Optical Performance: Precision Redefined
At the heart of this lens lies a 16mm nominal focal length (adjustable from 13.76–17.16mm via the integrated liquid lens), delivering exceptional versatility across a 60mm to 8m working distance range. Paired with a bright F6.4 aperture (F6.9–F7 with liquid lens engaged), it ensures consistent light transmission for crisp, clear imaging in both bright and low-light industrial environments.
Key optical benchmarks include:
Ultra-low distortion: A remarkable 0.2% maximum distortion at 570nm reference wavelength, ensuring pixel-perfect accuracy for dimensional measurement, defect detection, and high-detail imaging tasks.
Broad wavelength compatibility: Supports 435–680nm working wavelengths, covering the visible spectrum for versatile imaging applications from barcode scanning to scientific visualization.
6MP high resolution: Delivers sharp, detailed imagery ideal for industrial quality control, robotics guidance, and automated metrology.
Compact, Industry-Leading Design
Built for integration into space-constrained vision systems, the M12Li16-F6.4A features a 18.13mm total track length (TTL) and a standard M12×0.5 mount (weighing just 6g), making it perfect for compact automation setups, portable imaging devices, and embedded vision systems.
Additional design highlights:
Φ9.2mm image circle: Optimized for 1/1.8" sensors with a 15° maximum chief ray angle (CRA), ensuring seamless sensor compatibility and uniform light distribution.
78% relative illumination: Minimizes vignetting across the entire image frame, delivering consistent brightness from center to edge for reliable analysis.
Precision back focal length (BFL): 5mm (including 0.55mm CG) allows flexible integration with diverse sensor modules, simplifying system design and installation.
Industrial-Grade Durability & Reliability
Engineered to thrive in harsh industrial environments, this liquid lens offers exceptional temperature resilience:
Operating temperature: -20°C to +70°C (sustained performance in extreme cold/heat).
Storage temperature: -40°C to +85°C (safe handling and long-term storage).
The liquid lens autofocus technology eliminates moving mechanical parts, enabling:
Lightning-fast focus adjustment: Sub-millimeter precision focus shifts in milliseconds, critical for high-cycle automation and dynamic imaging scenarios.
Maintenance-free operation: Reduced wear and tear translates to lower downtime and longer service life, ideal for 24/7 industrial operations.
