M12 Wide Angle Lens Applications

Core Application Scenes

This 3.1mm M12 wide angle lens is designed for applications where maximizing scene coverage from a compact camera position is more important than minimizing optical distortion. Its 128° diagonal and 99° horizontal FOV allow a single camera to capture a substantially wider area than conventional longer-focal-length M12 lenses.

The lens is particularly suitable for embedded panoramic cameras, compact robotics vision modules, indoor area monitoring, smart IoT cameras, and visual navigation systems. Its 0.2m minimum object distance also makes it practical for relatively close-range scenes where the camera needs to observe a large area from a short installation distance.

For mobile or robotic systems, the wide field of view can help reduce blind spots and provide broader environmental awareness. This makes the lens a suitable optical component for selected Robotics Vision systems and compact visual sensing platforms.

Designed for ultra-wide embedded imaging, panoramic sensing, and close-range area coverage applications.

Compatible Device List

• Embedded Wide-Angle Cameras: Suitable for compact camera modules requiring broad scene coverage.
• Robotics Vision Modules: Can provide wider environmental visibility for compact mobile robots and robotic platforms.
• Panoramic Monitoring Cameras: Suitable for indoor spaces where one camera needs to cover a broad area.
• Smart IoT Vision Devices: The compact M12 configuration supports integration into space-constrained connected devices.
• Visual Navigation Systems: The wide FOV can help capture more of the surrounding environment for selected navigation and sensing applications.
• Compact Inspection Cameras: Useful for close-range observation where a broad viewing area is required rather than highly focused imaging.

Wide-Angle FOV and Sensor Matching

The lens is designed for a 1/3″ image format and provides 128° diagonal, 99° horizontal, and 63° vertical FOV. Its 3.1mm focal length is optimized for broad scene coverage, making sensor selection and camera placement particularly important during system design.

Because field of view depends on both focal length and sensor dimensions, engineers can use TOWIN’s FOV Calculator to estimate the expected image coverage before finalizing the camera configuration.

Frequently Asked Questions

Q: What type of lens is this?

A: This is a 3.1mm M12 wide angle fixed focal lens designed for compact camera modules requiring broad scene coverage and a small optical footprint.

Q: What is the field of view of this 3.1mm M12 lens?

A: The lens provides a 128° diagonal, 99° horizontal, and 63° vertical field of view when used with the specified 1/3″ image format.

Q: What sensor size is compatible with this lens?

A: The lens is specified for a 1/3″ image format and provides its stated FOV performance with this sensor size.

Q: Is this lens a low distortion lens?

A: No. The specified optical distortion is below 36%, so this model should not be positioned as a dedicated low distortion lens. Its optical design prioritizes broad field-of-view coverage.

Q: Is this a fisheye lens?

A: No. Although the lens provides a very wide 128° diagonal FOV, it should not automatically be classified as a fisheye lens. The product is better positioned as a wide angle M12 lens based on its specified optical characteristics.

Q: What is the minimum object distance of this lens?

A: The specified M.O.D. is 0.2m, making it suitable for relatively close-range imaging applications where a wide area needs to be captured from a short working distance.

Q: What does the IR Cut structure mean?

A: The lens uses an IR Cut structure for visible-light imaging applications. IR Cut filtering is different from an IR corrected optical design and should not be interpreted as IR correction.

Q: Can this M12 wide angle lens be customized?

A: TOWIN can evaluate customized optical and mechanical requirements for OEM and ODM camera projects. For specific sensor, housing, FOV, or integration requirements, contact TOWIN with the project specifications.

Product Selection Reference

When selecting a 3.1mm M12 wide angle lens, engineers should evaluate field of view, sensor format, working distance, resolution, distortion, and available installation space together. This model is optimized around broad scene coverage, providing 128° diagonal and 99° horizontal FOV on a 1/3″ sensor.

The 0.2m minimum object distance makes it particularly useful when a camera must capture a large nearby area, while the compact M12×0.5 interface simplifies integration into embedded camera assemblies.

For engineers comparing focal lengths and viewing coverage, the Focal Length Calculator can help evaluate how focal length affects the resulting field of view. Additional information about optical parameters is available in the Lens Basics section.
