3.3mm M12 Low Distortion Lens Applications

Core Application Scenes

This 3.3mm M12 ultra low distortion lens is designed for applications where a wide viewing angle is required but strong geometric deformation is undesirable. Its TV distortion below -0.5% makes it particularly valuable for vision systems that need to maintain relatively straight lines and consistent object proportions across the image.

In compact machine vision systems, the 86° horizontal FOV allows the camera to observe a broad inspection area without relying on extreme fisheye optics. This can be useful for close-range inspection of workpieces, equipment interfaces, packaging, assemblies, and other objects where the camera must be installed relatively close to the target.

The 0.2m M.O.D. also makes the lens suitable for short-distance embedded imaging. For robotic systems, the combination of 3.3mm focal length and low distortion can provide a wider view of a robot’s working area while maintaining more predictable image geometry for vision algorithms.

For industrial embedded cameras, the compact M12x0.5 mount and 22.49mm T.T.L. help engineers integrate the lens into small camera housings and equipment where optical space is restricted. The F2.7 fixed aperture provides a stable optical configuration without the mechanical complexity of a variable iris.

The particularly low < -0.5% distortion specification also makes this lens relevant to applications where images may be used for measurement, alignment, object localization, or machine vision preprocessing. Compared with a strongly distorted fisheye image, the lower geometric distortion can reduce the need for aggressive software correction.

Designed for low-distortion wide-area inspection, compact machine vision, robotic perception, and embedded industrial imaging applications.

For sensor matching, the Sensor Guide provides useful information about image formats and sensor coverage. The Lens Selection Guide can also help compare focal length, sensor size, working distance, and FOV requirements.

Since distortion is one of this lens’s key specifications, engineers can learn more about optical distortion through the Distortion Guide when evaluating image geometry for machine vision applications.

If the required scene coverage is not yet confirmed, the FOV Calculator can be used to estimate the relationship between sensor size, focal length, working distance, and field of view.

Frequently Asked Questions

Q: What type of lens is the 3.3mm M12 lens?
A: This fixed‑focal, wide‑angle, ultra‑low‑distortion M12 lens serves compact imaging systems, offering 3MP resolution for 1/2.5″ sensors.

Q: What is the field of view of this 3.3mm lens?
A: With the AR0233 sensor configuration, the lens provides a 96° diagonal FOV, 86° horizontal FOV, and 60° vertical FOV.

Q: How low is the distortion of this lens?
A: The specified TV distortion is below -0.5%. This is one of the key characteristics of the lens and makes it suitable for applications where accurate image geometry is important.

Q: Is the 3.3mm 96° lens a fisheye lens?
A: No. Although the lens provides a 96° diagonal field of view, its distortion is specified below -0.5%. It is therefore better classified as a wide angle low distortion lens rather than a fisheye lens.

Q: Which sensor is this M12 lens designed for?
A: The FOV data is specified with the 1/2.5″ AR0233 sensor. The lens should be evaluated with the actual camera sensor and image circle requirements before final integration.

Q: What applications benefit from less than 0.5% distortion?
A: Low distortion can be valuable in image-based measurement, alignment, object localization, inspection, and other computer vision applications where excessive geometric deformation can affect image processing.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.2m, or 200mm. This supports relatively close-range imaging while maintaining a broad viewing area.

Q: Can this lens be used in machine vision systems?
A: Yes. Boasting 3MP resolution, 86° horizontal FOV, <‑0.5% distortion and compact M12 mount, it fits compact machine vision and embedded inspection systems. Verify sensor, working distance, FOV and inspection accuracy for proper selection.
