3.1mm M12 Wide Angle Lens Applications

Core Application Scenes

This 3.1mm M12 automotive wide angle lens is developed for vehicle camera applications where maximum scene coverage is required from a compact optical module. Its 162° diagonal field of view enables the camera to capture a very broad area, making it suitable for close-range vehicle monitoring and wide-area visual perception.

This lens excels for camera positions that prioritize a broad viewing area over a narrow, long‑distance field of view. The 0.2m minimum object distance also supports relatively close-range imaging, making the lens practical for cameras monitoring the area immediately around a vehicle.

Its IP69K protection is an important feature for demanding automotive installations. Unlike lenses built solely for general‑indoor or protected camera modules, this design fits environments that face road spray, dust, moisture, and frequent high‑pressure cleaning.

For automotive perception systems requiring broad visual coverage, the lens can be integrated into ADAS solutions and other vehicle-mounted vision architectures where compact mechanical dimensions and environmental protection are important.

Compatible Device List

• Automotive Exterior Cameras: IP69K protection makes the lens suitable for camera modules installed in exposed vehicle locations where water, dust, and cleaning processes may be encountered.
• Wide-Angle Vehicle Monitoring Cameras: The 162° diagonal FOV allows a single camera to monitor a broad surrounding area from a compact mounting position.
• Parking Assistance Cameras: The 0.2m M.O.D. supports close-range imaging around the vehicle, helping capture nearby objects and environmental details.
• Embedded Automotive Camera Modules: The M12x0.5 mount and 15.76mm T.T.L. provide a compact optical configuration for space-limited designs.
• Rugged Vehicle Vision Systems: IP69K protection makes the lens suitable for applications requiring resistance to harsh outdoor operating conditions.
• Custom OEM Camera Assemblies: The fixed focal length and compact M12 structure can be integrated into dedicated automotive camera designs.

Designed for wide-angle automotive monitoring, parking assistance, and rugged exterior vehicle camera applications.

Wide-Angle Optical Design

The combination of a 3.1mm focal length and 162° diagonal FOV gives this lens an exceptionally broad viewing range while maintaining a compact optical package. This configuration is useful when the camera needs to observe a large surrounding area without using multiple narrow-angle lenses.

The specified TV distortion of less than -29% is significantly different from the extreme distortion characteristics normally associated with dedicated fisheye designs. For this reason, this model is positioned as a wide angle lens rather than a fisheye lens.

When evaluating the lens for a specific camera module, engineers should consider the relationship between sensor size, image format, focal length, and field of view. The Sensor Guide provides additional information about sensor and lens matching, while the Lens Selection Guide can help with lens selection based on application requirements.

For projects where field of view needs to be calculated before selecting a lens, the FOV Calculator can also be used to evaluate the required viewing geometry.

Frequently Asked Questions

Q: What type of lens is this 3.1mm M12 model?
A: It is a fixed focal length M12 automotive wide angle lens with a 162° diagonal field of view and IP69K protection.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides an extremely wide 162° diagonal field of view, this model is positioned as a wide angle lens rather than a fisheye lens. Its specified TV distortion is less than -29%.

Q: What is the field of view of this automotive lens?
A: With the OX03C10 sensor, the lens provides approximately 162° diagonal, 115° horizontal, and 72° vertical field of view.

Q: Why is IP69K protection useful for automotive applications?
A: IP69K protection is designed for demanding environments involving dust, moisture, water exposure, and high-pressure cleaning. This makes the lens suitable for rugged exterior vehicle camera applications.

Q: What is the mounting interface?
A: The lens adopts an M12x0.5 mount; this mounting format serves compact embedded camera modules and automotive vision systems widely.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.4 aperture and fixed iris, providing a stable optical configuration for dedicated camera systems.

Q: What image sensor is used for the FOV specification?
A: The specified field of view is based on the OX03C10 sensor. The actual FOV and image performance should be confirmed with the final sensor and camera module configuration.

Q: Can this lens be customized for an OEM automotive camera?
A: Towin can evaluate optical and mechanical requirements for OEM projects, including sensor matching, FOV, housing integration, and environmental requirements. Customers can contact Towin to discuss a specific project.
