Low Distortion Lens – S11011803640

S11011803640 is Low distortion lens for machine vision, 1/1.8″ M12/S-Mount lens, 44° 6-Megapixel F4.0 fixed-iris security/surveillance lens.

11mm 6MP M12 Low Distortion Machine Vision Lens

This 11mm M12 fixed focal lens is designed for 1/1.8″ image sensors and 6MP imaging applications that require controlled image coverage and low geometric distortion. With a 44° diagonal field of view and TV distortion below 1%, it provides a balanced optical configuration for localized inspection and machine vision applications.

The F4.0 fixed iris, 0.3m minimum object distance, and compact M12x0.35 mount make this lens suitable for embedded cameras and space-constrained vision systems where a stable fixed focal length is preferred.

11mm M12 Low Distortion Lens Applications

Core Application Scenes

The 11mm focal length offers a more controlled viewing area than shorter M12 lenses, making it suitable when the inspection target occupies a defined portion of the scene. With distortion below 1%, the lens can help preserve object geometry in applications where excessive image deformation could affect visual analysis.

For machine vision inspection, this optical configuration can be used for component checking, assembly verification, surface inspection, packaging inspection, and localized object recognition. The 6MP resolution provides sufficient image detail for many compact industrial imaging systems, while the F4.0 fixed aperture provides a straightforward configuration for controlled lighting environments.

The 0.3m M.O.D. makes the lens appropriate for applications where the camera is positioned relatively close to the target but does not require extreme near-field focusing. Its M12x0.35 mount and 15.45mm T.T.L. are also advantageous for integrating the lens into compact camera housings.

When determining whether 11mm is the appropriate focal length, engineers should consider the sensor size, working distance, target dimensions, and required field of view. The Lens Selection Guide can help with the optical selection process.

Frequently Asked Questions

Q: What sensor size is this 11mm M12 lens designed for?
A: The lens is designed for a 1/1.8″ image format and provides 6MP resolution.

Q: What field of view does the 11mm lens provide?
A: It provides a 44° diagonal, 36° horizontal, and 27° vertical field of view.

Q: Is the 11mm M12 lens suitable for machine vision?
A: Yes. Its 6MP resolution, <1% distortion, fixed focal length, and 1/1.8″ image format make it suitable for various compact machine vision applications.

Q: Is this an ultra-low distortion lens?
A: It provides low distortion with a specified value below 1%. For applications requiring extremely low distortion, optical performance should be compared with the specific requirements of the inspection system.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.3m, making it suitable for relatively close-range and medium-distance inspection setups.

Q: What is the difference between M12x0.35 and M12x0.5?
A: Both are M12-class threaded mounts, but they use different thread pitches. M12x0.35 has a 0.35mm pitch, so the camera housing or holder must be designed to match this thread specification.

Q: Is the 11mm lens suitable for wide-angle applications?
A: It is not primarily a wide-angle lens. Its 44° diagonal field of view is better suited to controlled, localized imaging rather than very broad scene coverage.

Q: How do I determine whether 11mm is the right focal length?
A: Compare the sensor size, working distance, target dimensions, and required field of view. The Focal Length Calculator can help estimate the focal length needed for a specific imaging setup.
