Low Distortion Lens – CCL1218MPR

CCL1218MPR 18mm 3MP M12 Low Distortion Lens with <0.1% distortion, F10 aperture and 25° FOV for precision inspection and measurement imaging.

18mm 3MP M12 Ultra-Low Distortion Fixed Focal Lens

This 18mm 3MP M12 Low Distortion Lens is designed for compact imaging systems that require extremely low geometric distortion and a controlled, narrow field of view. With distortion below 0.1%, an F10 fixed aperture, and a 18mm focal length, it provides highly stable image geometry for precision inspection, measurement-oriented imaging, and other applications where maintaining accurate object shape and position is critical.

Product Core Highlights

• Ultra-low distortion <0.1% provides highly accurate image geometry for precision imaging applications.
• 18mm fixed focal length delivers a controlled 25° diagonal field of view on a 1/2″ sensor.
• 3MP resolution supports detailed image capture for inspection and recognition tasks.
• F10 fixed aperture provides a controlled optical configuration for applications requiring consistent imaging conditions.
• Compact M12 × 0.5 interface enables integration into space-constrained embedded imaging systems.

Product Applications

The key advantage of this 18mm M12 lens is its extremely low distortion below 0.1%. Rather than being designed for broad scene coverage, the lens provides a focused field of view that is better suited to applications where a defined target area needs to be captured with minimal geometric deformation.

For precision inspection and measurement-oriented imaging, the ultra-low distortion performance helps maintain the relative shape and position of objects within the captured image. This makes the lens a potential choice for component inspection, dimensional observation, edge detection, alignment, pattern analysis, and localized quality-control imaging.

The 18mm focal length and 25° diagonal FOV are suitable when the camera is positioned at a moderate working distance and the target occupies a defined portion of the image. The 0.2m minimum object distance also provides flexibility for relatively close-range imaging compared with longer-distance-only optical configurations.

The fixed F10 aperture provides a stable optical setup for controlled inspection environments where lighting conditions can be managed independently. For applications requiring different focal lengths or wider fields of view, TOWIN offers a broader range of M12 Lenses.

When integrating this lens with a camera, sensor format and field of view should be evaluated together with the required working distance. Since this lens is designed for a 1/2″ image format, the sensor should be matched accordingly. TOWIN’s Sensor Guide provides additional information about sensor and lens compatibility.

For determining the required viewing area, the FOV Calculator can be used to evaluate the relationship between sensor size, focal length, and working distance.

Frequently Asked Questions

Q: What is the focal length of this M12 lens?
A: This lens uses a fixed 18mm focal length, providing a 25° diagonal field of view on a 1/2″ sensor.

Q: What makes this lens a low distortion M12 lens?
A: Its specified distortion is below 0.1%, providing exceptionally controlled image geometry compared with standard imaging lenses.

Q: Is the distortion really below 0.1%?
A: Yes. The supplied specification states distortion of <0.1%. This makes the lens particularly attractive for applications where geometric accuracy is important.

Q: What sensor format is supported?
A: The lens is specified for a 1/2″ image format.

Q: Is this an 18mm wide-angle lens?
A: No. Its 25° diagonal, 20° horizontal, and 15° vertical FOV provide a relatively narrow and focused viewing area rather than a wide-angle perspective.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.2m, or approximately 200mm.

Q: Why does this lens use an F10 aperture?
A: The F10 fixed aperture provides a controlled optical configuration that can be useful in imaging systems with managed illumination and consistent operating conditions.

Q: Is this lens suitable for machine vision?
A: Its 3MP resolution and exceptionally low <0.1% distortion make it a potential fit for localized machine vision inspection and measurement applications. Final suitability depends on the sensor, working distance, lighting, and required field of view.

Why Choose an Ultra-Low Distortion M12 Lens?

In precision imaging, geometric distortion can affect the apparent position, shape, and dimensions of objects in an image. A distortion specification of <0.1% provides highly controlled image geometry, making this lens particularly interesting for applications where accurate visual representation is more important than wide scene coverage.

For a deeper explanation of how distortion influences optical performance, see TOWIN’s Distortion Guide.

The 18mm focal length also differentiates this product from shorter M12 lenses by providing a more concentrated viewing area.
