Wide Angle Lens – CCL13037MP

3.7mm 102° Wide angle 1/3″ 4MP F1.8 Low F-number M12/S-Mount Lens (Fast Lenses), security surveillance lens.

3.7mm M12 4MP Wide Angle Lens

This 3.7mm M12 wide angle lens is designed for compact camera systems that require a broad field of view without using a large optical assembly. Supporting a 1/3″ sensor and 4MP resolution, it provides a 102° diagonal FOV with a fixed F1.8 aperture, making it suitable for embedded vision, compact monitoring, robotics, and other space-constrained imaging applications. The M12x0.5 mount and 6G optical construction provide a practical combination of compact integration, optical performance, and production flexibility.

For systems requiring a compact wide-angle optical solution, this lens can be integrated with TOWIN’s M12 Lenses and other application-specific optical configurations.

M12 Wide Angle Lens Core Highlights

• 102° Wide Field of View: The 3.7mm focal length delivers 102° diagonal, 76° horizontal, and 59° vertical FOV for broad scene coverage.
• 4MP Imaging Performance: Supports 4MP cameras and compact imaging systems requiring practical image detail across a wide viewing area.
• F1.8 Fixed Aperture: The F1.8 aperture provides a useful balance between light transmission, depth of field, and compact optical design.
• Compact M12x0.5 Mount: The standard M12 interface simplifies integration into small cameras, embedded vision modules, and space-constrained devices.
• High Relative Illumination: Relative illumination above 92% helps maintain more consistent brightness toward the image edges.

M12 Wide Angle Lens Applications

Embedded Wide-Angle Vision

The 3.7mm focal length and 102° diagonal FOV make this lens suitable for compact cameras that need to capture a relatively large scene from a limited installation space. It can be used where a conventional longer focal length lens would provide insufficient coverage.

Typical applications include embedded cameras, smart devices, compact inspection modules, and indoor monitoring systems where camera size and viewing coverage are both important.

Robotics & Mobile Vision

Compact robots and mobile platforms often require a wide viewing angle to observe surrounding objects while maintaining a small camera footprint. The 3.7mm M12 configuration can provide broad scene coverage for navigation support, obstacle awareness, robotic monitoring, and compact vision modules.

For more demanding robotic imaging requirements, the lens can also be considered alongside TOWIN’s Robotics Vision solutions.

Compact Security & Monitoring Cameras

The 76° horizontal FOV provides useful lateral scene coverage for compact monitoring cameras installed in relatively confined environments. The fixed F1.8 aperture and 4MP capability make the lens suitable for applications such as indoor monitoring, smart access devices, equipment monitoring, and compact security cameras.

Machine Vision & Embedded Inspection

This lens can also be used in selected compact machine vision configurations where broad scene coverage is more important than extremely low geometric distortion. The 4MP resolution, manual focus, M12x0.5 mount, and 0.3m MOD provide flexibility for close-range embedded inspection and visual monitoring.

For applications where distortion is a critical measurement parameter, users should compare this lens with TOWIN’s Low Distortion Lens range.

Designed for Compact Wide-Angle Vision Applications

Designed for compact wide-angle vision applications, this 3.7mm M12 lens is particularly suitable when the camera must cover a broad area while maintaining a small optical footprint.

Compatible Devices

• Compact M12 camera modules
• Embedded vision cameras
• Robotics vision cameras
• Indoor monitoring cameras
• Smart security cameras
• IoT imaging devices
• Compact inspection cameras

Sensor & Field-of-View Matching

This lens is optimized for 1/3″ image sensors and provides:

• 102° diagonal FOV
• 76° horizontal FOV
• 59° vertical FOV

The 3.7mm focal length is suitable when a relatively wide scene needs to be captured from a short working distance. When selecting a camera and lens combination, sensor format, mounting position, working distance, and required coverage should be considered together.

Frequently Asked Questions

Q: What type of lens is the 3.7mm M12 lens?
A: It is a fixed focal length M12 lens designed for 1/3″ sensors, with a 102° diagonal FOV and 4MP resolution.

Q: What is the field of view of this 3.7mm lens?
A: The lens provides a 102° diagonal FOV, 76° horizontal FOV, and 59° vertical FOV when used with its specified 1/3″ image format.

Q: Is this 3.7mm M12 lens suitable for wide-angle applications?
A: Yes. Its 102° diagonal field of view makes it suitable for compact wide-angle cameras, embedded vision systems, robotics, and monitoring applications requiring broad scene coverage.

Q: Is this lens a low-distortion lens?
A: No. The specified distortion is -24%, so this model should not be selected when very low geometric distortion is a primary requirement. TOWIN offers dedicated low-distortion optical solutions for those applications.

Q: What sensor size is this M12 lens designed for?
A: The lens is designed for 1/3″ image sensors and provides its specified 102°/76°/59° FOV with this image format.

Q: Does the lens support manual focusing?
A: Yes. The lens uses manual focus, allowing the optical focus to be adjusted according to the installation distance and application requirements.

Q: What camera interface does this lens use?
A: It uses an M12x0.5 mount, making it compatible with camera modules and imaging systems designed for standard M12 lens interfaces.

Q: Can this lens be used for machine vision?
A: Yes, it can be used in selected compact machine vision and embedded inspection systems where a wide field of view is required. However, applications requiring precise dimensional measurement should consider the lens’s -24% distortion specification.
