Low Distortion Lens – S12011803328

S12011803328 is Low-distortion 8-Megapixel M12-mount lens with a 1/1.8″ format, 41° diagonal FOV, and F2.8 aperture for security surveillance.

12mm 8MP M12 Low Distortion Machine Vision Lens

This 12mm M12 fixed focal lens is designed for 1/1.8″ image sensors and 8MP machine vision applications requiring high image detail and excellent geometric control. With TV distortion below 0.2%, the lens maintains highly consistent image geometry across its 41° diagonal field of view.

The F2.8 aperture and 0.1m minimum object distance make this lens particularly suitable for close-range inspection, while its M12x0.5 mount supports integration into compact industrial and embedded camera systems.

Product Core Highlights

• 8MP resolution supports detailed imaging with 1/1.8″ sensors.
• <0.2% TV distortion provides excellent geometric accuracy for inspection.
• 12mm focal length delivers controlled 41° diagonal image coverage.
• 0.1m M.O.D. supports close-range inspection and compact camera positioning.
• F2.8 aperture provides a practical balance between light transmission and depth of field.

12mm M12 Low Distortion Lens Applications

Core Application Scenes

The defining characteristic of this lens is its combination of 8MP resolution and <0.2% TV distortion. This makes it suitable for machine vision applications where maintaining accurate object geometry is important, such as dimensional inspection, component verification, and localized automated inspection.

The 12mm focal length provides a controlled 41° diagonal field of view, making it appropriate for systems that need to focus on a defined inspection region rather than capture a very broad scene. The 0.1m M.O.D. is especially useful for close-range applications where the camera must be installed near the inspection target.

With an F2.8 aperture and fixed iris, the lens is well suited to stable imaging environments with controlled illumination. Its M12x0.5 mounting interface also makes it practical for compact machine vision cameras, embedded vision modules, and customized OEM imaging equipment.

For engineers matching the lens to a particular sensor and working distance, the Lens Selection Guide provides guidance on focal length, field of view, and other important optical parameters.

Frequently Asked Questions

Q: What sensor size is this 12mm M12 lens designed for?
A: It is designed for a 1/1.8″ image format and supports 8MP resolution.

Q: How low is the distortion of this lens?
A: The specified TV distortion is below 0.2%, making it well suited to applications requiring strong geometric control.

Q: What is the field of view of the 12mm lens?
A: The lens provides a 41° diagonal, 33° horizontal, and 25° vertical field of view.

Q: Is this lens suitable for close-range machine vision?
A: Yes. Its 0.1m minimum object distance makes it suitable for relatively close inspection setups, especially when combined with the low-distortion optical design.

Q: Is the 12mm M12 lens a fisheye lens?
A: No. The 41° diagonal field of view and <0.2% distortion indicate a controlled fixed focal optical design rather than a fisheye configuration.

Q: What does the M12x0.5 mount mean?
A: M12x0.5 refers to an M12-class threaded mount with a 0.5mm thread pitch. The camera housing or lens holder must use the corresponding thread specification.

Q: Can this lens be used for dimensional inspection?
A: Yes. The combination of 8MP resolution and <0.2% TV distortion can be advantageous for dimensional and geometric inspection tasks.

Q: How do I determine whether 12mm is the correct focal length?
A: The appropriate focal length depends on sensor size, working distance, target dimensions, and required field of view. The Focal Length Calculator can be used to estimate the required focal length.
