Description
Enhance your long-range monitoring and precision inspection capabilities with our 2MP 25mm F2.0 M12 telephoto lens. Specifically engineered for 1/3″ format sensors, this high-performance fixed focal lens provides a narrow, focused 14° diagonal field of view, making it exceptional for capturing distant details. Featuring premium IR Corrected optics, it guarantees perfect day-and-night focus co-axiality without shifting, offering a low-distortion (<1.5%) imaging solution for intelligent transportation (ITS), long-range CCTV surveillance, and industrial machine vision.
Key Features & Product Highlights
- Long-Range Narrow Field of View: Features a 25mm narrow-angle focal length (11° Horizontal FOV) that brings distant targets into sharp focus, filling the gap where standard wide-angle lenses fail.
- Advanced IR Corrected Performance: Eliminates daylight-to-night focus shift under infrared illumination, delivering crisp 2MP resolution 24/7 without refocusing.
- Excellent Optical Distortion Control (<1.5%): Keeps geometric warping below 1.5% to ensure accurate measurement calculations and reliable target recognition.
- Bright F2.0 Aperture Intake: Fast F2.0 aperture maximizes light transmission for superior image contrast and lower noise under low-light or nighttime conditions.
- Rigid Manual Focus M12 Chassis: Combines a secure M12x0.5 thread with manual focus tuning, making it highly stable against industrial vibrations and moving equipment.

Target Applications & Compatible Devices
Core Application Scenarios
This 25mm IR corrected M12 lens is specifically engineered for narrow-angle, long-distance target capturing where spatial tracking or detail amplification is crucial. In Intelligent Transportation Systems (ITS), it provides the precise reach required for multi-lane speed enforcement cameras and high-speed toll booth license plate recognition (LPR). In CCTV surveillance, it excels at factory perimeter fencing line security and corridor monitoring, where standard wide lenses introduce too much environmental clutter. Additionally, for Industrial Machine Vision, it serves as an excellent tool for close-up macro imaging from a safe distance, enabling robotic arms to inspect delicate components from a 0.2m proximity without risking mechanical collision.
Compatible Device List
- Sensors: Optimized for 1/3″, 1/2.8″, and 1/4″ format standard 1080P Full HD CMOS sensors (such as Sony IMX series, OmniVision, and Onsemi).
- Security & ITS Hardware: License plate capture cameras, toll gate monitoring modules, and long-range bullet CCTV setups.
- Industrial Vision Systems: Automated factory sorting lines, smart barcode scanners, and high-accuracy surface defect detection modules.
- Specialized Automation: Parking gate enforcement systems, long-distance automated guided vehicle (AGV) path tracking, and alignment sensors.
Designed for Long-Range ITS License Plate Recognition and Industrial Machine Vision applications.
Frequently Asked Questions
Q: What is the main benefit of an IR Corrected lens for 24/7 security?
A: Standard lenses bend visible light and infrared night light differently, causing the nighttime image to go blurry. Our IR Corrected optical design keeps both light spectrums on the exact same focal point, ensuring a razor-sharp 2MP image day and night.
Q: Can this 25mm lens be used on a 1/2.8-inch sensor module?
A: Yes, it is fully compatible with 1/2.8″ and 1/3″ sensors. When paired with a slightly larger 1/2.8″ sensor, the field of view will widen marginally while maintaining peak sharpness.
Q: Does this telephoto M12 lens support adjustable zooming?
A: No, this is a fixed focal lens with a set 25mm focal length. It features manual focus adjustment to lock onto targets at varying distances, but the optical magnification factor is fixed.
Q: Is the 0.2m minimum object distance helpful for macro applications?
A: Yes, an M.O.D. of 20 centimeters is highly unique for a 25mm long lens. It allows industrial micro-cameras to stay physically further away from hot or moving machinery while still getting a highly magnified close-up view.
Q: How does the <1.5% low distortion level affect computer vision algorithms?
A: Low optical distortion ensures that lines stay perfectly straight. This allows recognition software to instantly read barcodes, faces, or license plates without needing heavy digital correction.
Q: Can I request a modified IR cut filter or specialized anti-reflective coating?
A: Yes. We offer comprehensive OEM/ODM custom services. We can configure the lens with specific IR cut bands, dual-band filter arrays, or tailored mechanical mounts to fit your custom housings.
