Low Distortion Lens – S02112312022F

S02112312022F is Low distortion lens Wide-angle 12-Megapixel 1/2.3″ M12/S-Mount F2.2 CCTV lens with Built-In Filter for security surveillance.

2.1mm M12 Low Distortion Lens

This 2.1mm 12MP M12 low distortion lens is designed for compact imaging systems that require an exceptionally wide field of view without the extreme image deformation associated with conventional fisheye optics. With a 132° diagonal FOV, 120° horizontal FOV, and TV distortion below -5%, it provides broad scene coverage while maintaining practical image geometry.

Featuring an M12×0.5 mount, fixed F2.2 aperture, 0.1m minimum object distance, and 4G2P+IRCF optical construction, this lens is well suited to embedded cameras, compact wide-angle vision modules, and space-constrained imaging equipment.

2.1mm M12 Low Distortion Lens Applications

Core Application Scenes

This 2.1mm M12 low distortion lens is designed for compact vision systems where a wide viewing angle is required but excessive geometric distortion can reduce the usefulness of captured images. Its 120° horizontal FOV allows a single camera to cover a broad scene, while the TV distortion below -5% helps maintain recognizable shapes and spatial relationships.

The lens is particularly suitable for embedded wide-angle cameras, compact AI vision modules, smart monitoring devices, indoor panoramic monitoring, and robotic perception systems where installation space is limited. Compared with a conventional fisheye lens, its controlled distortion makes it more practical for applications that need wide coverage while retaining relatively natural image geometry.

With a 0.1m minimum object distance, it can also capture subjects at relatively close range. This makes it suitable for compact devices installed near the monitored area, such as smart equipment, access points, small inspection modules, and edge-AI camera systems.

For systems that require assistance selecting focal length and viewing coverage, the Lens Selection Guide and FOV Calculator can help engineers evaluate the relationship between focal length, sensor size, and field of view.

Compatible Device List

• Embedded Camera Modules: The M12×0.5 mount and 24.49mm TTL make the lens suitable for compact camera assemblies where optical space is restricted.

Frequently Asked Questions

Q: What type of lens is this 2.1mm M12 lens?
A: It is a fixed focal length, wide-angle M12 lens designed for 1/2.3″ sensors. Its low-distortion optical design provides broad coverage without relying on a typical fisheye projection.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a very wide 132° diagonal FOV, its TV distortion is specified below -5%, making it a low-distortion wide-angle lens rather than a conventional fisheye lens.

Q: What sensor size is this lens designed for?
A: The lens is designed for a 1/2.3″ image format and supports up to 12MP resolution according to the supplied specifications.

Q: What is the horizontal field of view?
A: The horizontal FOV is 120°, while the diagonal and vertical FOVs are 132° and 95°, respectively.

Q: What does the F2.2 fixed aperture mean for this lens?
A: The F2.2 fixed aperture provides a constant optical opening without requiring manual or automatic iris adjustment. This simplifies integration into compact camera modules.

Q: What is the minimum object distance of this M12 lens?
A: The minimum object distance is 0.1m, allowing the lens to capture subjects at relatively close working distances.

Q: What applications are suitable for this low distortion lens?
A: Typical applications include embedded vision, compact AI cameras, robotics vision, smart monitoring, wide-area indoor imaging, and other space-constrained imaging systems requiring broad coverage with controlled distortion.

Q: How can I select the appropriate focal length for my camera system?
A: Focal length should be selected according to the sensor format, required field of view, working distance, and target dimensions. Towin’s Focal Length Calculator can help estimate the focal length required for a specific imaging setup.
