UltraOpto 5.42mm focal length M12 imaging lense

UltraOpto’s M12-5.4F Series is a compact, high-performance fixed-focal industrial lens tailored for 1/3” sensors, designed for machine vision, inspection, and automation applications. With a 5.42mm focal length, multiple aperture options (F4.5/F5.4/F7/F8/F11), and low distortion, this lens delivers reliable imaging quality for diverse industrial workflows.

Core Optical Performance

The M12-5.4F series features a 5.42mm fixed focal length with a choice of 5 aperture settings, enabling precise control over light intake and depth of field. At the optimal working distance of 350mm, it offers a horizontal field of view (FOV) of 47.7° and vertical FOV of 36.7°, with a low distortion of just -0.7% for accurate detail capture in inspection, measurement, and quality control tasks.

• 3MP high resolution:

• Delivers sharp, crisp imagery ideal for barcode scanning, robotics guidance, and defect detection.

• Wide working distance range:

• Supports focus from 100mm to infinity, suitable for both close-up inspection and long-range imaging scenarios.

• 80% relative illumination:

• Minimizes vignetting across the image frame, ensuring uniform brightness from center to edge for reliable analysis.

Compact, Industrial-Grade Design

Built with a total track length (TTL) of 22.81–23.13mm and a standard M12×0.5 full-thread mount, this lens integrates seamlessly into compact vision systems, embedded devices, and portable imaging setups.

4.44mm back focal length (BFL):

Optimized for easy integration with 1/3” sensors, simplifying system design and calibration.

• Durable full-thread construction:

• 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 and continuous 24/7 use.

Versatile Aperture Options for Every Application

• F4.5:

• Maximum light intake for low-light environments and fast shutter speeds.

• F5.4 / F7:

• Balanced performance for general-purpose inspection and automation.

• F8 / F11:

• Extended depth of field for high-precision measurement and detailed imaging.
