Description
1/2.5″ 6.0mm 5MP F2.0 M12 Fixed Focal Lens
Achieve exceptional optical precision with our high-resolution 1/2.5″ 5MP 6.0mm M12 fixed focal lens. Meticulously engineered for 5-megapixel (2K/4K scaling) image sensors, this lens delivers outstanding edge-to-edge sharpness and highly accurate geometry with a well-controlled distortion of less than 19%. Featuring a standard M12x0.5 mount and an integrated IRCF (Infrared Cut Filter), it filters out ambient light interference to capture vibrant, true-to-life colors. Its 54° horizontal field of view is optimized for mid-range tracking, making it an excellent choice for advanced security surveillance, facial recognition terminals, and precision industrial machine vision.
Key Product Highlights
- 5MP High-Definition Resolution: Engineered with ultra-fine optical resolve power to perfectly match 5-megapixel CMOS sensors, ensuring crystal-clear details for inspection and tracking.
- Low-Distortion Optical Design: Features a controlled geometric distortion of <-19%, delivering natural, linear images ideal for algorithmic analytics and text recognition.
- Mid-Range 6.0mm Narrow Perspective: The 67° diagonal (54° horizontal) narrow field of view concentrates pixels on the target object, offering greater detail at longer distances than wide-angle lenses.
- Integrated IR Cut Filter (IRCF): Built-in premium IRCF effectively eliminates infrared color distortion during daytime, yielding pristine contrast and precise color accuracy.
- Bright F2.0 Fixed Aperture: Balanced F2.0 iris structure allows ample light transmission to maintain crisp, low-noise imagery even in standard commercial indoor lighting.

Applications & Device Compatibility
Core Application Scenarios
This 5MP 6.0mm M12 lens is purpose-built for applications requiring mid-range distance monitoring and strict geometric accuracy. It excels in AI facial recognition turnstiles, smart access control gates, and biometric payment kiosks, where minimizing edge stretching is critical for deep-learning algorithmic mapping. Additionally, its narrow 54° horizontal field of view makes it highly efficient for Automatic Number Plate Recognition (ANPR) and parking lot entry barrier gates to capture license plates cleanly. In industrial settings, it is a proven optical solution for automated factory assembly lines, optical character recognition (OCR) scanning, and automated parcel sorting systems where high dimension accuracy is mandatory.

Frequently Asked Questions
- Q: What are the main benefits of a 6.0mm lens compared to a 2.8mm or 3.6mm lens?
- A: A 6.0mm lens provides a narrower field of view (54° H), which acts as a optical zoom compared to wide-angle lenses. It focuses the sensor’s pixels onto a smaller area, allowing you to recognize faces, license plates, or small barcodes at a greater distance.
- Q: How does the <-19% distortion benefit my system?
- A: This low distortion rating ensures that lines remain straight and proportions stay natural. It is highly beneficial for machine vision software, OCR, and facial recognition, as it minimizes the need for software-based digital dewarping.
- Q: Can this 1/2.5″ lens be used with smaller sensor sizes?
- A: Yes, it is fully compatible with 1/2.7″, 1/2.8″, and 1/3″ sensors. When used with a smaller sensor, the field of view will crop slightly narrower, but the image will exhibit outstanding edge-to-edge sharpness.
- Q: Is the IRCF (IR Cut Filter) removable on this model?
- A: No, this model features a built-in fixed IRCF designed for standard daytime color accuracy. If your application requires 24/7 day/night switching via an external mechanical ICR switcher, please contact our team for a customized version without the built-in filter.
- Q: How do I adjust the focus on this M12 lens?
- A: Focus is adjusted manually during assembly. You simply screw the lens into the M12 thread holder until the camera feed displays a perfectly sharp image at your target working distance, then secure it using a locking nut or optical adhesive.
