Wide Angle Lens – S02212814520

S02212814520 – 2.2mm Wide-angle 5-megapixel CCTV HD lens, F2.0 S-Mount Lenses with Low F-number (Fast Lenses), security surveillance lens.

5MP 2.2mm M12 Wide Angle Fisheye Lens

This 5MP 2.2mm M12 Wide Angle Fisheye Lens is designed for compact camera systems that require an extremely wide field of view. Supporting 1/2.8″ and 1/3″ image formats, it delivers up to 167° diagonal FOV on a 1/2.8″ sensor and 155° on a 1/3″ sensor, making it suitable for wide-area monitoring, embedded vision, robotics, smart security, and other applications where maximum scene coverage is important.

With an F2.0 aperture, M12×0.5 mount, and compact 2G5P optical construction, this fixed focal lens provides a practical solution for space-constrained camera designs. Explore more M12 lenses for additional focal lengths and imaging requirements.

M12 Wide Angle Fisheye Lens Core Highlights

• Ultra-wide 167° FOV: The 2.2mm focal length provides extremely broad scene coverage on a 1/2.8″ sensor, reducing blind spots in wide-area imaging.
• 5MP imaging capability: Supports detailed image capture for compact camera systems requiring more than basic surveillance resolution.
• Dual sensor-format compatibility: Designed for both 1/2.8″ and 1/3″ image formats, providing greater flexibility when selecting an image sensor.
• Compact M12 interface: The M12×0.5 mount is well suited to embedded cameras and space-constrained vision devices.
• F2.0 fixed aperture: Provides a balanced optical configuration for wide-angle monitoring and continuous imaging applications.

For applications requiring broad coverage, this lens can also be compared with TOWIN’s wide angle lenses and fisheye lenses.

M12 Wide Angle Fisheye Lens Applications

Core Application Scenes

The combination of a 2.2mm focal length, up to 167° diagonal FOV, and 5MP resolution makes this M12 fisheye lens particularly suitable when a camera needs to capture a large scene from a short installation distance.

Designed for wide-area smart security applications. The ultra-wide FOV can help cover entrances, rooms, corridors, retail spaces, and other areas where minimizing blind zones is more important than maintaining low geometric distortion.

It is also suitable for compact embedded vision systems where the camera module has limited installation space but still requires broad environmental awareness. The 1/2.8″ and 1/3″ sensor compatibility allows system designers to select an appropriate sensor without changing the basic lens platform.

For robotics and autonomous equipment, the wide viewing angle can support environmental perception, obstacle awareness, indoor navigation, and near-field scene monitoring. See TOWIN’s robotics vision solutions for related optical applications.

Frequently Asked Questions

Q: What is the maximum FOV of this 2.2mm M12 lens?
A: On a 1/2.8″ sensor, the lens provides a maximum specified FOV of 167° diagonal, 145° horizontal, and 90° vertical.

Q: Can this lens be used with a 1/3″ image sensor?
A: Yes. The lens supports both 1/2.8″ and 1/3″ image formats. On a 1/3″ sensor, the specified FOV is 155° diagonal, 135° horizontal, and 80° vertical.

Q: Is this an M12 fisheye lens?
A: Yes. Its 2.2mm focal length and up to 167° diagonal FOV place it in the ultra-wide fisheye lens category, making it suitable for applications requiring very broad scene coverage.

Q: Is this lens suitable for low-distortion machine vision?
A: This lens is designed primarily for ultra-wide coverage rather than precision low-distortion imaging. Fisheye optics generally introduce significant geometric distortion, so applications requiring accurate dimensional measurement should consider a dedicated low-distortion lens.

Q: What type of camera uses this M12 lens?
A: It is suitable for compact cameras, smart security modules, embedded vision systems, robotics cameras, IoT imaging devices, and other systems using an M12×0.5 interface.

Q: What is the advantage of the F2.0 aperture?
A: The F2.0 aperture provides a practical balance between light transmission, optical size, and system design requirements for wide-angle camera applications.

Q: Is this lens suitable for robotics vision?
A: Yes. Its very wide FOV can be useful for environmental awareness, indoor navigation, obstacle monitoring, and other robotics applications where broad near-field coverage is required.
