Description
Achieve ultra-sharp optical precision and compact integration with our 1/2.3″ 5MP 7.5mm M12 Low Distortion Lens. Expertly engineered for high-resolution machine vision, factory automation (FA), and commercial surveillance systems, this industrial-grade camera lens delivers a full 5-Megapixel resolving power. Featuring an optical distortion profile of less than 1% (<-1%) and a tailored 55° diagonal field of view, it ensures highly accurate geometric data capture without aggressive edge warping. With a bright F2.4 aperture, short 11.1mm TTL, and standard M12x0.5 thread, it serves as the ultimate optical upgrade for smart vision systems requiring strict dimensional accuracy and robust durability.
Key Features & Product Highlights
- 5MP High-Definition Resolving Power: Optically optimized to match large 1/2.3″ sensors, capturing precise details and fine textures with rich contrast.
- Low Distortion Performance (<1%): Eliminates geometric barrel bending to ensure straight lines and true-to-life tracking for automated inspection.
- Optimized 45° Horizontal Field of View: Provides a balanced narrow-to-medium field of view (F.O.V.), making it ideal for targeted, long-distance target scanning.
- Compact 11.1mm TTL Design: Streamlined total track length enables seamless deployment in extremely tight camera enclosures and thin board systems.

Target Applications & Device Compatibility
Core Application Scenarios
This 5MP 7.5mm fixed focal M12 lens is meticulously engineered for environments where spatial dimensions and data accuracy are paramount. It serves as an exceptional choice for industrial machine vision setups, such as PCB component alignment, automated retail self-checkout systems, and robotic sorting arms on fast-moving conveyor belts. The narrow 45° horizontal view makes it highly efficient for hallway CCTV surveillance, turnstile facial recognition gates, and automated parking access tracking where wide-angle distortions would compromise security details. Additionally, its incredibly short 0.1m minimum focus capability allows it to excel in close-up industrial scanning and benchtop medical inspection arrays.

Frequently Asked Questions
Q: What are the main benefits of using a 7.5mm lens with a 45° horizontal field of view?
A: Compared to wide-angle lenses, a 7.5mm focal length provides a narrower, more concentrated 45° view. This brings distant objects closer and allows the camera to capture high-density details with much greater pixel clarity, which is essential for reading barcodes or identifying faces at a distance.
Q: Why is a distortion rating of <-1% important for this optical lens?
A: In machine vision and automated inspection, geometric distortion can cause errors in measurements or AI recognition. A profile under 1% ensures straight edges appear completely straight on the sensor, eliminating the need for CPU-heavy digital lens corrections.
Q: What is the advantage of the 2G2P lens construction?
A: The 2G2P configuration combines 2 glass elements and 2 plastic elements. The glass elements provide excellent thermal stability and scratch resistance to prevent focus drift in harsh industrial climates, while the plastic elements utilize aspherical designs to cut weight and maximize cost efficiency.
Q: Can I use this 1/2.3″ lens on a standard 1/3″ security camera sensor?
A: Yes, it is fully backward-compatible. When you pair this lens with a smaller 1/3″ sensor, your field of view will simply narrow slightly due to the sensor crop factor. However, you will achieve outstanding center sharpness and zero corner vignetting.
Q: How close can an object be for this lens to achieve sharp focus?
A: The Minimum Object Distance (M.O.D.) is 0.1 meters (10 cm). This exceptionally short working distance allows the lens to capture highly detailed macro images of objects placed almost right against the lens, perfect for close-up component inspection.
Q: Does this lens come with an integrated infrared (IR) filter?
A: This specific model is configured with a high-transmittance visible light coating. For 24/7 day/night security applications, we recommend pairing it with an external electronic IR-cut switcher on your camera board, or you can contact us to order a custom version with a built-in 650nm IR filter.
