UltraOpto M12-4.5F Series Industrial Lens
UltraOpto’s M12-4.5F Series is a versatile 4.5mm fixed focal length industrial lens designed for 1/3” sensors, ideal for machine vision, industrial inspection, and automation imaging applications. Available in multiple aperture versions (F4.0 / F5.6 / F7.0 / F8.0 / F11), this lens balances compact design, reliable performance, and flexible configuration to meet diverse industrial imaging needs.
Core Optical Performance
The M12-4.5F series features a 4.5mm fixed focal length with interchangeable aperture options (F4.0 to F11), offering precise control over depth of field and light intake for varying industrial environments. At a working distance of 200mm, it delivers a horizontal field of view (FOV) of 55.2° and vertical FOV of 42.9°, with a low distortion of just 1.3% for accurate detail capture in inspection and measurement tasks.
3MP high resolution:
Delivers sharp, crisp imagery for quality control, barcode scanning, and robotics guidance.
Wide working distance range: Supports focus from 100mm to infinity, suitable for both close-up inspection and long-range imaging.
>80% relative illumination:
Minimizes vignetting across the entire image frame, ensuring uniform brightness from center to edge.
Compact, Industrial-Grade Design
Built with a total track length (TTL) of 23.35–23.56mm and a standard M12×0.5 full-thread mount, this lens integrates seamlessly into compact vision systems, embedded devices, and portable imaging setups.
4.5mm back focal length (BFL): Optimized for easy integration with 1/3” sensors, simplifying system design and calibration.
Durable construction: Full-thread design ensures secure mounting and compatibility with standard industrial camera modules.
Wide temperature resilience: Operates reliably from -30°C to +70°C, suitable for harsh industrial environments.
Versatile Aperture Options for Every Application
The series offers five aperture variants to match specific imaging requirements:
F4.0: Maximum light intake for low-light environments and fast shutter speeds.
F5.6 / F7.0: Balanced performance for general-purpose inspection and automation.
F8.0 / F11: Extended depth of field for high-precision measurement and detailed imaging.
This flexibility makes the M12-4.5F series ideal for applications including logistics scanning, factory automation, robotics vision, and scientific imaging workflows.
