Low Distortion Lens – S12012702528

S12012702528 is Low-distortion 4-Megapixel M12-mount CCTV lens for machine vision, featuring 12mm focal length and 29° diagonal field of view.

12mm M12 Low Distortion Lens

This 12mm 4MP M12 low distortion lens is designed for compact imaging systems that require focused scene coverage and very short-range imaging capability. With a 1/2.7″ image format, 25° horizontal FOV, and distortion below -0.7%, it provides controlled image geometry for applications where the camera needs to concentrate on a defined target.

Its 0.05m minimum object distance makes this lens particularly suitable for close-range imaging, while the M12×0.5 mount, 23.23mm TTL, and F2.8 fixed aperture support integration into compact camera modules and space-constrained vision equipment.

Product Highlights at a Glance

• 4MP resolution delivers detailed imaging for compact visual systems.
• < -0.7% distortion provides controlled image geometry for defined target areas.
• 0.05m minimum object distance supports very close-range imaging.
• 12mm fixed focal length provides focused target framing with limited background coverage.
• M12×0.5 compact mount simplifies integration into small camera assemblies.

12mm M12 Low Distortion Lens Applications

Core Application Scenes

This 12mm M12 low distortion lens is particularly suited to applications where the camera is installed close to the subject and needs to capture a defined region with controlled perspective. Its exceptionally short 0.05m minimum object distance allows the lens to work with targets positioned only a few centimeters from the camera, providing an advantage for compact near-field imaging systems.

The 25° horizontal FOV and 14.5° vertical FOV create a relatively concentrated viewing area. Rather than covering a large environment, the lens is better suited to close-up equipment monitoring, small-part observation, compact inspection modules, access-control imaging, and embedded visual sensing where the target occupies a specific region of the image.

The low distortion specification of below -0.7% is useful when the shape and position of the target need to remain visually consistent across the image. Combined with 4MP resolution, the lens can provide sufficient detail for recognition, monitoring, and image-analysis tasks involving relatively small objects.

The compact optical configuration is also beneficial when the camera must be installed inside or immediately adjacent to equipment. Its 5.82mm back focal length and 23.23mm TTL provide useful mechanical information for OEM designers developing small camera housings or embedded vision assemblies.

For projects where the target size, working distance, and required coverage need to be evaluated before selecting a focal length, Towin’s Lens Selection Guide provides practical guidance. The FOV Calculator can also help engineers estimate the visible area at a given working distance.

Frequently Asked Questions

Q: What type of lens is this 12mm M12 lens?
A: It is a 12mm fixed focal M12 lens designed for 1/2.7″ sensors. It combines 4MP resolution with distortion below -0.7% and is particularly suitable for focused and close-range imaging.

Q: What is the minimum object distance of this lens?
A: The minimum object distance is 0.05m, or 5cm. This makes the lens suitable for applications where the camera must be positioned very close to the target.

Q: What is the field of view of the 12mm lens?
A: On a 1/2.7″ sensor, the lens provides 29° diagonal, 25° horizontal, and 14.5° vertical FOV.

Q: Is this lens suitable for close-up machine vision?
A: It can be used in compact close-range vision systems where the 0.05m MOD, 4MP resolution, and controlled distortion meet the application’s optical requirements. Final suitability depends on target size, working distance, lighting, and camera sensor characteristics.

Q: How much distortion does this M12 lens have?
A: The specified distortion is below -0.7%, providing controlled geometric deformation for defined target areas.

Q: What sensor format is this lens designed for?
A: The specified image format is 1/2.7″, with a maximum image circle of Φ7.3mm and a 4MP resolution rating.

Q: What does the 5.82mm BFL specification mean?
A: BFL is the distance from the lens rear reference point to the image plane under defined optical conditions. It serves as a key mechanical parameter for lens‑to‑camera‑module integration.

Q: How can I calculate the coverage of this 12mm lens at my working distance?
A: Field coverage depends on the sensor size, focal length, and working distance. Towin’s FOV Calculator can be used to estimate the visible area for a specific camera setup.
