6.1MM FOCAL LENGTH M12 IMAGING LENSE

UltraOpto M12-6.0H Series Industrial Lens

UltraOpto’s M12-6.0H Series is a versatile 6.1mm fixed focal length industrial lens designed for both 1/2" and 1/3" sensors, delivering 6MP resolution with multiple aperture options (F4.0 / F5.6 / F7.0 / F8.0 / F11). Built for industrial machine vision, inspection, and automation applications, this half-thread lens balances wide field of view, low distortion, and rugged reliability.


Core Optical Performance

This series features a 6.1mm fixed focal length with a choice of 5 aperture settings, enabling precise control over light intake and depth of field to suit diverse industrial environments. At the optimal working distance of 200mm, it offers a horizontal field of view (FOV) of 54.3° for 1/2" sensors (41.9° for 1/3" sensors), with a low distortion of -1.00% for accurate detail capture in inspection, measurement, and quality control tasks.
  • 6MP high resolution:

  • Delivers sharp, crisp imagery for demanding applications like barcode scanning, robotics guidance, and defect detection.


  • Dual sensor compatibility:

  • Optimized for both 1/2" (6.4×4.8mm) and 1/3" (4.8×3.6mm) sensors, offering flexibility across different camera modules.

  • Wide working distance range:

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

  • 65% relative illumination:

  • Ensures consistent brightness across the image frame, minimizing vignetting for reliable analysis.


Compact, Industrial-Grade Design

Built with a total track length (TTL) of 23.3–23.69mm and a standard M12×0.5 half-thread mount, this lens integrates seamlessly into compact vision systems, embedded devices, and portable imaging setups.


  • 5.0mm back focal length (BFL):

  • Optimized for easy integration with both 1/2" and 1/3" sensors, simplifying system design and calibration.

  • Durable half-thread construction:

  • Ensures secure mounting and compatibility with standard industrial camera modules, ideal for space-constrained applications.

  • 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

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 M12-6.0H series ideal for applications including logistics sorting, factory automation, robotics vision, and scientific imaging workflows.
