• 85° Wide-Angle FOV — Provides broad scene coverage without the extreme distortion associated with fisheye optics.
• IP67 Waterproof Protection — Supports outdoor automotive camera installations exposed to dust and water.
• 3.3mm Fixed Focal Length — Delivers consistent optical performance for dedicated camera modules.
• Compact M12x0.5 Mount — Enables straightforward integration into space-constrained camera assemblies.

3.3mm M12 IP67 Automotive Lens Applications

Core Application Scenes

This 3.3mm M12 low distortion automotive lens is designed for camera applications where wide-area coverage is required but strong fisheye distortion is undesirable. Its 85° diagonal field of view provides useful scene coverage while the specified TV distortion of less than -7% helps maintain more controlled image geometry.

This combination makes the lens particularly suitable for vehicle-mounted cameras that need to capture nearby surroundings while retaining relatively natural image proportions. Compared with an extreme fisheye design, the lower distortion characteristics can simplify image interpretation and downstream image processing when geometric consistency is important.

The 0.1m minimum object distance also supports close-range imaging, while the IP67 construction makes the lens suitable for exterior automotive camera modules exposed to rain, dust, and road moisture.

For automotive vision systems requiring controlled wide-angle imaging, this lens can be integrated into ADAS solutions where broad visual coverage and manageable optical distortion are both important.

Low-Distortion Optical Design

The defining feature of this lens is its combination of a 3.3mm focal length, 85° diagonal FOV, and less than -7% TV distortion. This configuration provides a wider viewing area while keeping geometric distortion substantially more controlled than an extreme fisheye optical system.

This makes the lens useful when the camera needs to observe a relatively large area but excessive bending of straight lines or strong fisheye effects would reduce image usability. The controlled distortion characteristics can be particularly valuable in applications involving object positioning, scene interpretation, and camera-based monitoring.

The lens is specified for a 1/4″ image format, with the listed FOV based on the AR0144 sensor. When selecting the lens for another sensor, engineers should verify the active sensor dimensions and image circle compatibility.

For more information about how distortion affects imaging performance, refer to the Distortion Guide. The Sensor Guide can help with sensor matching, while the Lens Selection Guide provides additional guidance when comparing focal length, sensor size, FOV, and application requirements.

The lens also uses an IRCF configuration. This indicates an IR Cut Filter configuration and should not be interpreted as a dedicated IR-corrected optical design.

Frequently Asked Questions

Q: What type of lens is this 3.3mm M12 model?
A: It is a fixed focal length M12 low distortion automotive lens with an 85° diagonal field of view and IP67 waterproof protection.

Q: What is the distortion of this M12 lens?
A: The specified TV distortion is less than -7%. This controlled distortion characteristic makes the lens suitable for applications where excessive wide-angle image deformation should be minimized.

Q: What is the field of view of this automotive lens?
A: With the AR0144 sensor, the lens provides approximately 85° diagonal, 70° horizontal, and 45° vertical field of view.

Q: What sensor format is this lens designed for?
A: The lens is specified for a 1/4″ image format, with the listed FOV measured using the AR0144 sensor.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.2 aperture and fixed iris, providing a stable optical configuration for dedicated camera modules.

Q: Is this lens suitable for outdoor automotive applications?
A: Yes. Its IP67 waterproof construction makes it suitable for automotive camera modules exposed to outdoor conditions involving dust and water.

Q: Does the IRCF specification mean the lens is IR corrected?
A: No. IRCF refers to an IR Cut Filter configuration. It should not be treated as equivalent to an IR-corrected optical design. The final spectral performance should be evaluated with the selected camera sensor.

Q: Can Towin customize this M12 automotive lens?
A: Towin can evaluate optical and mechanical requirements for OEM projects, including sensor matching, FOV, distortion targets, housing integration, and environmental requirements. Customers can contact Towin to discuss a specific project.
