Low Distortion Lens – S12012702780

S12012702780 is Low-distortion CCTV 5-Megapixel lens with M12/S-Mount, 12mm focal length, 31° diagonal F.O.V., and F8.0 aperture for security surveillance.

12mm M12 Low Distortion Lens

This 12mm F8.0 5MP M12 lens is designed for compact vision systems that require high-resolution imaging, low distortion, and precise close-range observation. With a 31° diagonal field of view on a 1/2.7″ sensor, less than 0.7% distortion, and a 0.05m minimum object distance, it provides controlled imaging for embedded inspection, recognition, and machine vision applications.

The fixed 12mm focal length and compact M12x0.5 mount make this lens easy to integrate into small camera modules where stable optical performance and accurate target framing are important.

12mm M12 Low Distortion Lens Applications

Core Application Scenes

This 12mm M12 lens is particularly suitable for close-range machine vision and embedded imaging where the camera needs to observe a defined target area without excessive perspective distortion. The 0.05m minimum object distance allows the lens to be positioned close to small components, labels, connectors, mechanical parts, or other inspection targets.

With 5MP resolution and distortion below 0.7%, the lens can support applications where image geometry and fine details are important. It can be used for small-part inspection, barcode and code reading, component recognition, equipment monitoring, and compact AI vision systems.

The F8.0 fixed aperture provides a controlled optical configuration for applications with stable lighting conditions. For projects requiring a more detailed selection of focal length, sensor size, and field of view, the Lens Selection Guide can help determine the appropriate optical configuration.

Designed for close-range machine vision and embedded inspection applications.

For compact camera platforms, this product can also be integrated with the broader M12 Lenses range when different focal lengths or optical characteristics are required.

Frequently Asked Questions

Q: What sensor size is this 12mm M12 lens designed for?
A: The specified field of view is based on a 1/2.7″ sensor, with a 31° diagonal, 27° horizontal, and 15° vertical field of view.

Q: Is this a low distortion lens?
A: Yes. The specified distortion is less than -0.7%, making it suitable for applications where geometric accuracy and controlled image deformation are important.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.05m, or 5cm, allowing the lens to capture targets at relatively short working distances.

Q: Is this lens suitable for machine vision?
A: Yes. Its 5MP resolution, fixed 12mm focal length, low distortion, and close focusing capability make it suitable for compact machine vision and inspection systems.

Q: What does the M12x0.5 mount mean?
A: M12x0.5 refers to the mechanical thread specification of the lens mount. It is commonly used for compact camera modules and embedded vision systems.

Q: Does the F8.0 aperture make this lens suitable for low-light applications?
A: F8.0 is a relatively small aperture, so the lens is better suited to systems with adequate or controlled illumination rather than applications where maximum light collection is required.

Q: What is the difference between the B.F.L. and T.T.L.?
A: B.F.L. is the back focal length from the rear optical reference to the image plane, while T.T.L. is the overall physical optical track length of the lens. Both are important when checking mechanical integration.
