Wide Angle Lens – CCL13024

Lightweight Wide Angle Lens for Portability CCTV lens 1/3″ M12 139°(D) 2.4mm F2.0 lens,Low F-number M12-Mount Lens

2.4mm M12 139° Wide Angle Lens

This 2.4mm M12 wide angle lens is designed for compact camera systems that require broad scene coverage while maintaining a more controlled field of view than extreme Wide Angle optics. With a 139° diagonal FOV, 104° horizontal FOV, 78° vertical FOV, and 1/3″ image format, it provides wide environmental visibility for embedded cameras, robotics, surveillance, and compact vision systems.

The F2.0 aperture, M12 × 0.5 mount, 5.5mm BFL, and 0.2m minimum object distance provide a practical optical configuration for compact camera modules. For additional compact optical solutions, explore TOWIN’s M12 Lenses.

M12 Wide Angle Lens Core Highlights

• 139° Ultra-Wide FOV – Captures a broad scene for environmental monitoring and spatial awareness applications.
• 2.4mm Short Focal Length – Provides extensive coverage in compact camera installations.
• F2.0 Aperture – Supports practical light gathering for indoor and general-purpose imaging environments.
• M12 × 0.5 Mount – Provides a compact and widely used mounting configuration for embedded camera modules.
• 5.5mm BFL & 0.2m MOD – Supports relatively close-range installation and compact optical integration.

M12 Wide Angle Lens Applications

This 2.4mm lens is positioned between conventional wide-angle optics and more extreme Wide Angle designs. Its 139° diagonal FOV provides extensive scene coverage, while the -39% optical distortion reflects the wide-angle optical design.

It is particularly useful when a camera needs to see a large surrounding area but the application does not require the extreme 170° coverage of a more aggressive Wide Angle lens.

Core Application Scenes

Designed for compact wide-angle monitoring applications, this lens can provide broad image coverage from a relatively small camera module.

Typical applications include:

• Compact indoor surveillance
• Embedded security cameras
• Mobile robot cameras
• Robotics environmental awareness
• Smart home cameras
• IoT vision devices
• Indoor area monitoring
• Short-range environmental observation
• Compact panoramic imaging
• Embedded vision systems

The 139° FOV can be useful for robotic systems that need broad peripheral visibility without using an extremely wide 170°-class Wide Angle lens. It can therefore support TOWIN’s Robotics Vision solutions in compact camera designs.

Compatible Devices

Embedded Camera Modules
The M12 × 0.5 mount makes this lens suitable for compact camera modules where optical space and mechanical dimensions are limited.

Robotics Cameras
The 104° horizontal FOV provides broad lateral visibility for mobile robots and compact robotic platforms.

Indoor Security Cameras
The wide-angle optical design can cover a relatively large indoor area from a close installation position, helping reduce blind zones.

Smart IoT Cameras
Its compact M12 configuration allows integration into small smart devices that require broad environmental visibility.

Compact Vision Systems
The short 2.4mm focal length can be used where a large scene needs to be captured without installing a large conventional lens assembly.

For applications requiring much lower geometric distortion, TOWIN also provides dedicated Low Distortion Lenses.

Wide-Angle Imaging and Distortion Considerations

With a 139° diagonal FOV, this lens is designed to capture significantly more of the surrounding environment than a conventional narrow-angle lens. The trade-off is its -39% optical distortion, which becomes more noticeable toward the image edges.

This makes the lens better suited to scene awareness, monitoring, and coverage-oriented imaging than precision measurement. When selecting a lens for machine vision, engineers should consider field of view and distortion together rather than evaluating focal length alone.

TOWIN’s Lens Selection Guide provides additional guidance on selecting suitable optical configurations, while the FOV Calculator can help estimate the required field of view.

Frequently Asked Questions

Q: What is the field of view of this 2.4mm M12 lens?
A: The lens provides a 139° diagonal FOV, 104° horizontal FOV, and 78° vertical FOV for broad-area imaging.

Q: Is this a Wide Angle lens?
A: Yes. Its 139° diagonal field of view and -39% optical distortion place it in the ultra-wide lens category.

Q: Is this a low-distortion M12 lens?
A: No. The specified optical distortion is -39%, so the lens should be positioned as a wide-angle solution rather than a low-distortion lens.

Q: What sensor size does this lens support?
A: The lens is designed for a 1/3″ image format and is suitable for compatible VGA-resolution camera systems.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.2m, making the lens suitable for relatively close-range monitoring and environmental observation.

Q: Is this lens suitable for robotics?
A: Yes. Its 104° horizontal FOV provides broad peripheral visibility, making it suitable for mobile robots and compact robotic platforms that require environmental awareness.

Q: What is the difference between this lens and a 170° Wide Angle lens?
A: This lens provides a narrower 139° diagonal FOV compared with a 170° Wide Angle design. It therefore offers broad coverage while using a less extreme ultra-wide optical configuration.

Q: Can this lens be used for precision machine vision inspection?
A: It can be used for machine vision applications where broad scene coverage is important, but its -39% distortion makes it unsuitable for applications requiring highly accurate dimensional measurement.
