Description
Achieve ultimate metrology-grade precision with our flagship 12MP 50mm M12 Zero Distortion Lens. Engineered for large-format 1/1.8″ CMOS sensors, this ultra-high-resolution telephoto lens delivers a tightly focused 9° horizontal field of view, empowering your system to isolate distant targets with 12-megapixel clarity. Boasting an incredible optical distortion rating of < 0.1%, it provides perfect geometric linearity without requiring software correction. With a relatively short Minimum Object Distance (M.O.D.) of 0.3m, this compact fixed focal lens is the premier choice for sub-micron industrial machine vision, factory automation (FA), and long-range intelligent transportation systems (ITS).
Key Highlights
- 12MP Metrology-Grade Sharpness: Engineered to fully resolve high-density 12-megapixel sensors, capturing micro-defects and sub-micron edge features without contrast degradation.
- Virtually Zero Distortion (< 0.1%): Delivers nearly perfect geometric mapping across the sensor, completely eliminating pixel bending and stretching for flawless dimensional inspection.
- 50mm Ultra-Telephoto Precision: Provides an ultra-narrow 9° horizontal view to monitor target zones from long working distances, protecting hardware from harsh environments or moving machinery.
- 0.3m Short M.O.D. for Telephoto: Breaks the limitations of traditional 50mm lenses by allowing tight macro-telephoto focusing just 30cm away, maximizing spatial pixel density in compact enclosures.

Applications & Compatibility
Core Application Scenarios
This 12MP 50mm M12 zero distortion lens is purpose-built for applications requiring extreme measurement accuracy, remote target alignment, and high-pixel-density localized inspections. It excels in Factory Automation (FA) and Industrial Machine Vision systems for solar cell crack detection, semiconductor wafer alignment, and micro-component profile measurement, where the < 0.1% distortion ensures zero algorithm calibration overhead. Its narrow-angle design also renders incredible value for Intelligent Transportation Systems (ITS) demanding long-range Automatic Number Plate Recognition (ANPR) and face-matching access control terminals. Furthermore, its rugged construction and 0.3m short focus make it ideal for high-magnification medical diagnostic instruments and laboratory benchtop scanning setups.

Frequently Asked Questions
- Q: Why is a < 0.1% distortion rating important for machine vision?
- A: A distortion rate below 0.1% is considered “Zero Distortion.” It means that straight lines remain perfectly straight on the sensor. This allows AI systems and measurement algorithms to calculate distances and sizes accurately without wasting processing power on digital lens correction.
- Q: What are the benefits of a 50mm focal length on a small M12 mount?
- A: It provides a powerful telephoto effect within an incredibly compact format. It narrows the horizontal field of view to 9° on a 1/1.8″ sensor, allowing you to mount your camera far away from high-temperature or high-vibration hazard zones while maintaining a tight focus on the subject.
- Q: Can this 50mm telephoto lens capture objects close to the camera?
- A: Yes. Unlike most long focal lenses that require meters of working distance, this lens features an optimized Minimum Object Distance (M.O.D.) of just 0.3 meters (30cm). This allows for macro-telephoto close-ups inside tight industrial machinery.
- Q: Does this 12MP lens feature auto-focus capabilities?
- A: No, this is a manual focus lens with a fixed iris and fixed zoom. Eliminating internal moving parts ensures maximum ruggedness and guarantees the focus won’t drift or slip during high-vibration robotic arm movements.
- Q: Will this lens cause vignetting or dark corners on a 1/1.8″ sensor?
- A: No. The lens is optically designed from the ground up for the 1/1.8″ image format, ensuring full, uniform brightness and absolute sharpness across the entire sensor array.
- Q: Is there an integrated filter built into this lens?
- A: This model features highly transparent, multi-coated glass elements without a default filter to maximize light transmission. However, custom filter integrations (such as an IR Cut Filter or specific bandpass filters) can be provided upon request.
