8mm focal length M12 Autofocus Liquid Lens
UltraOpto’s 8mm focal length M12 Autofocus Liquid Lensis a compact, high-performance autofocus solution engineered for 2/3” sensors, delivering reliable performance across a broad range of industrial and machine vision applications.
Core Optical Specifications
This lens features an 8.1mm nominal focal length (adjustable 7.7–8.2mm with the liquid lens) and a bright F3.4 aperture, maintaining consistent light transmission even at varying working distances from 60mm to 2m. At 570nm (the reference wavelength), it offers sharp, distortion-controlled imaging with a maximum distortion of just 3.5%, ensuring accurate detail capture for inspection, measurement, and analysis tasks.
Compact, Precision-Engineered Design
Built with a total track length (TTL) of only 19.32mm and a standard M12 mount, the lens integrates seamlessly into compact vision systems without sacrificing optical quality. Its 18.5° maximum chief ray angle (CRA) ensures compatibility with a wide range of image sensors, while 70% relative illumination minimizes vignetting for uniform brightness across the entire 11.2mm image circle.
Robust Performance for Demanding Environments
Designed for industrial use, the lens operates reliably across a temperature range of -20°C to +70°C, with a storage range of -40°C to +85°C. The integrated liquid lens enables fast, precise autofocus without moving mechanical parts, enhancing durability and reducing maintenance needs in high-cycle applications. With 6MP resolution support, it delivers crisp, high-detail imagery ideal for quality control, logistics scanning, and scientific imaging workflow.
