2.2mm M12 170° Fisheye Wide Angle Lens

This 2.2mm M12 fisheye lens is designed for ultra-wide imaging systems that require maximum scene coverage from a compact camera module. With a 170° diagonal FOV, 130° horizontal FOV, 95° vertical FOV, and 1/3″ image format, it captures an exceptionally broad viewing area for panoramic monitoring, robotics, embedded vision, and spatial awareness applications.

The M12 × 0.5 mount, 4.35mm BFL, and compact optical configuration make this lens suitable for small camera systems where a very wide viewing angle is more important than maintaining low geometric distortion. For additional compact optical solutions, explore TOWIN’s M12 Lenses.

Ultra Wide Angle Lens Core Highlights

• 170° Ultra-Wide FOV – Provides exceptionally broad scene coverage for panoramic and spatial awareness imaging.
• 2.2mm Short Focal Length – Captures a large viewing area from a relatively short camera-to-subject distance.
• M12 × 0.5 Compact Mount – Supports integration into miniature embedded cameras and space-constrained camera housings.
• Megapixel Resolution – Provides suitable image detail for compact monitoring and embedded vision applications.
• 5G Optical Construction with IR Cut – Supports a compact optical design for visible-light imaging applications.

Ultra Wide Angle Lens Applications

The defining characteristic of this lens is its extremely wide 170° diagonal field of view. Rather than prioritizing geometric accuracy, the optical design prioritizes capturing as much of the surrounding environment as possible from a single camera position.

The -87% optical distortion is therefore an intentional characteristic of its fisheye design. This makes the lens particularly useful for applications where scene coverage, peripheral visibility, and environmental awareness are more important than precise object geometry.

Core Application Scenes

Designed for ultra-wide spatial awareness applications, this lens can provide extensive environmental visibility from a compact camera position.

Typical applications include:

• Panoramic indoor monitoring
• Compact security cameras
• Robotics and mobile robots
• Embedded vision systems
• Smart home cameras
• IoT imaging devices
• Surrounding-area observation
• Indoor navigation and environment perception
• Wide-area occupancy monitoring
• Compact panoramic imaging

For robotics applications, the 170° FOV can help a camera observe a much larger surrounding area with a single optical module. It can therefore be considered for TOWIN’s Robotics Vision solutions where broad environmental visibility is required.

Compatible Devices

Miniature Embedded Cameras
The M12 × 0.5 mount allows the lens to be integrated into compact camera modules where installation space is limited.

Robotic Vision Cameras
The 170° diagonal FOV can help mobile robots monitor their surrounding environment and improve peripheral visibility.

Indoor Security Cameras
The ultra-wide optical design can cover a broad indoor area from a relatively close installation position, reducing the need for multiple camera viewpoints in some applications.

Smart IoT Cameras
The compact M12 configuration is suitable for smart devices requiring a very wide viewing angle within a small enclosure.

Panoramic Imaging Systems
The fisheye optical design can capture a large portion of the surrounding scene for applications that prioritize coverage over rectilinear image geometry.

For applications where the image must preserve object shape and measurement accuracy, a low-distortion design would be more appropriate. TOWIN provides dedicated Low Distortion Lenses for those requirements.

Optical Design Considerations

A 170° field of view requires a fundamentally different optical approach from conventional machine vision lenses. As the viewing angle becomes extremely wide, significant geometric distortion is introduced toward the edges of the image.

With -87% optical distortion, this lens should therefore be selected when maximum field coverage is the primary requirement rather than dimensional measurement or accurate image geometry.

When selecting an ultra-wide lens, engineers should consider the relationship between focal length, sensor size, field of view, working distance, and distortion. TOWIN’s Lens Selection Guide can help with the initial selection process, while the FOV Calculator can be used to evaluate field-of-view requirements.

Frequently Asked Questions

Q: What is the field of view of this 2.2mm M12 lens?
A: The lens provides a 170° diagonal FOV, 130° horizontal FOV, and 95° vertical FOV, making it suitable for extremely wide-angle and fisheye imaging.

Q: Is this lens a fisheye lens?
A: Yes. Its 170° diagonal field of view and -87% optical distortion are characteristic of an ultra-wide fisheye optical design.

Q: Why does this lens have -87% distortion?
A: The high distortion results from the extremely wide 170° field of view. The design prioritizes maximum scene coverage rather than maintaining rectilinear image geometry.

Q: What sensor size is this M12 lens designed for?
A: This lens is designed for 1/3″ image formats and is suitable for compatible compact camera sensors.

Q: Is this lens suitable for precision machine vision inspection?
A: It can be used in machine vision systems when extremely wide scene coverage is required, but it is not the ideal choice for precision measurement or dimensional inspection because of its high optical distortion.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, allowing the lens to be used for relatively close-range environmental and embedded imaging applications.

Q: Does the IR cut element mean that this lens is IR corrected?
A: No. The 5G + IR cut construction indicates an IR-cut element for visible-light imaging, but it should not be described as an IR-corrected lens.

Q: What applications are best suited to this lens?
A: Typical applications include panoramic monitoring, robotics, compact security cameras, embedded vision, smart devices, IoT cameras, and spatial awareness systems requiring extremely broad scene coverage.
