UltraOpto M12-35F Series Industrial Lens
UltraOpto’s M12-35F Series is a precision-engineered 35.01mm fixed focal length industrial lens designed for both 1/1.8" and 2/3" sensors, delivering 6MP resolution with flexible aperture options (F5.6 / F7.0 / F8.0 / F11). Built for high-precision machine vision, metrology, and automation applications, this full-thread lens combines ultra-low distortion, exceptional edge illumination, and rugged durability to meet the strictest industrial imaging requirements.
Core Optical Performance
The M12-35F series features a 35.01mm fixed focal length with four aperture settings, enabling precise control over light intake and depth of field across diverse industrial environments. At the optimal working distance of 400mm, it offers a horizontal field of view (FOV) of 10.7° for 1/1.8" sensors (12.6° for 2/3" sensors), with distortion as low as 0.10%—ensuring pixel-perfect accuracy for dimensional measurement, defect detection, and high-detail imaging tasks.
6MP High Resolution:
Delivers sharp, crisp imagery ideal for barcode scanning, robotic guidance, and critical quality control applications.
Dual Sensor Compatibility:
Seamlessly works with 1/1.8" (7.2×5.4mm) and 2/3" (8.45×7.07mm) sensors, offering flexibility for different camera system designs.
Broad Working Distance Range:
Supports focus from 100mm to infinity, covering close-up inspection and long-range monitoring scenarios.
95% Relative Illumination:
Industry-leading low vignetting ensures consistent brightness from center to edge, even in wide-field imaging.
Compact, Industrial-Grade Design
Built with a total track length (TTL) of 41.09–57.53mm and a standard M12×0.5 full-thread mount, this lens integrates effortlessly into compact vision systems, embedded devices, and portable imaging setups.
7.39mm Back Focal Length (BFL):
Optimized for easy integration with 1/1.8" and 2/3" sensors, simplifying system calibration and design.
Durable Full-Thread Construction:
Provides a secure, stable mount compatible with standard industrial camera modules, ideal for high-vibration industrial environments.
Wide Temperature Resilience:
Operates reliably from -30°C to +70°C, ensuring continuous 24/7 performance in harsh industrial settings.
Flexible Aperture Options for Targeted Applications
The series offers four aperture variants to match specific imaging needs:
F5.6:
Balanced light intake for general automation and inspection tasks.
F7.0:
Versatile performance for mid-range imaging and standard detection workflows.
F8.0 / F11:
Enhanced depth of field for precise dimensional measurement and detail-oriented inspection.
This adaptability makes the M12-35F series ideal for logistics sorting, factory automation, robotic vision, and scientific imaging applications.
