Description
Achieve exceptional clarity and geometrical precision at a distance with our 3MP 25mm F2.5 M12 IR Corrected Lens. Tailored for 1/3″ format sensors, this high-performance fixed focal lens provides a narrow 14° diagonal field of view, ideal for isolating far-off targets without pixel degradation. Featuring an advanced IR Corrected optical design and a near-zero distortion profile (<-0.5%), it delivers razor-sharp imaging 24/7. This makes it the premier choice for Intelligent Transportation Systems (ITS), industrial machine vision, and long-range CCTV surveillance.
Key Features & Product Highlights
- Narrow 25mm Telephoto Reach: Delivers focused magnification with a tight 11° horizontal FOV, capturing high-detail imagery from afar where wide lenses fail.
- Near-Zero Optical Distortion (<-0.5%): Eliminates edge stretching and geometric bending, providing highly accurate raw data for computer vision algorithms.
- Full 3MP High-Definition Clarity: Engineered with premium optical layers to resolve sharp 3-Megapixel details, ensuring crisp contrast across the entire sensor.
- Advanced Nighttime IR Correction: Features true infrared-corrected optics to maintain a constant focal point under both daylight and IR night illumination.
- Stable Manual Focus Architecture: Built with a standard M12x0.5 thread and precision manual focus adjustment, resisting harsh vibrations on industrial lines.

Target Applications & Compatible Devices
Core Application Scenarios
This 3MP low distortion M12 IR Corrected Lens is specifically engineered for long-distance targeting and precision optical alignment where geometric accuracy cannot be compromised. In Intelligent Transportation Systems (ITS), its narrow-angle design provides the precise distance coverage needed for speed enforcement, toll booth auditing, and long-range license plate recognition (LPR). For Industrial Machine Vision and FA, it serves as an excellent close-up macro lens that can be safely positioned at a distance, allowing robotic arms to inspect delicate PCB parts from a 0.2m minimum object distance without risking collision. Additionally, it excels in high-security CCTV perimeter fencing lines and narrow corridors where minimizing surrounding background clutter is essential.
Compatible Device List

Designed for Long-Range ITS License Plate Recognition and Precision Machine Vision applications.
Frequently Asked Questions
Q: Why is an M12 IR Corrected lens necessary for 24/7 tracking?
A: Standard telephoto lenses focus infrared night-light differently than visible daylight, creating blurry night images. Our IR Corrected optical coating ensures both light spectrums converge on the exact same focal plane, keeping your 3MP feed perfectly sharp day and night.
Q: How does the <-0.5% distortion level benefit automated industrial inspection?
A: Distortion bends lines and skews dimensions, making automated software calculations inaccurate. With a near-zero distortion profile under 0.5%, your machine vision camera can take precise measurements without wasting processing power on digital dewarping.
Q: Can this 25mm fixed focal lens be used on a 1/2.7-inch sensor?
A: Yes, it is compatible. Mounting it on a slightly larger 1/2.7″ sensor will expand the field of view by a small margin while retaining excellent contrast and resolution across the active area.
Q: Does this M12 lens feature motorized zooming capability?
A: No, this is a fixed focal telephoto lens with a set 25mm focal length. It features a manual focus adjustment barrel to calibrate the lens to your specific target distance, but the optical zoom factor is locked.
Q: What is the practical value of the 0.2m Minimum Object Distance (M.O.D.)?
A: An M.O.D. of 20cm on a 25mm lens provides a high optical magnification effect. It allows industrial cameras to read micro-barcodes or inspect fine solder lines while keeping the camera housing safely away from moving machine parts.
Q: Are custom IR filters or alternative mechanical barrel lengths available?
A: Yes, we offer full OEM/ODM customization services. We can tailor the lens with specific IR-cut bands, dual-band filter designs, or modify the mechanical casing to seamlessly fit your specialized enclosures.
