Low Distortion Lens – S16012502216

S16012502216 is 16mm High-precision low-distortion lens, 1/2.5″ M12/S-mount lenses, fixed aperture F1.6, 5-megapixel resolution CCTV lens.

16mm F1.6 M12 Low Distortion Lens

This 16mm F1.6 M12 low distortion lens is a high-resolution fixed focal lens designed for 1/2.5″ sensors and 5MP imaging systems. With a 25° diagonal field of view, less than 2.5% distortion, and a maximum Φ8.0mm image circle, it is well suited to compact imaging applications requiring focused target coverage and controlled image geometry.

Product Highlights at a Glance

• 16mm focal length provides focused target coverage for applications requiring a narrower viewing angle.
• 5MP resolution supports detailed imaging with compatible 1/2.5″ sensors.
• <2.5% distortion helps maintain controlled image geometry across the captured scene.
• F1.6 aperture provides strong light-gathering capability for variable-light environments.
• 55% relative illumination helps maintain useful brightness toward the image periphery.

M12 Low Distortion Lens Applications

Core Application Scenes

This 16mm M12 low distortion lens is designed for imaging systems that need to concentrate the camera’s field of view on a specific target area. Its 22° horizontal and 12° vertical FOV provide considerably more focused coverage than a conventional wide-angle lens, making it appropriate when the camera needs to observe a defined object or region rather than a large surrounding scene.

The combination of 16mm focal length and less than 2.5% distortion makes this lens suitable for applications where target geometry should remain reasonably controlled. Potential uses include component observation, equipment monitoring, code inspection, localized quality inspection, and compact measurement-oriented imaging systems.

Its 5MP resolution and maximum Φ8.0mm image circle are designed around 1/2.5″ sensor applications. This provides system designers with a compact M12 optical option when a larger lens format is undesirable but higher-resolution imaging and a relatively narrow field of view are required.

The F1.6 aperture also provides useful light-gathering capability for indoor imaging environments. Combined with a 0.2m minimum object distance, the lens can be positioned relatively close to the monitored target, which is useful for compact equipment and space-constrained installations.

For applications involving dimensional analysis or geometric image accuracy, engineers can review the Distortion Guide to understand how lens distortion affects imaging performance. The Lens Selection Guide can also help compare focal length, sensor size, FOV, and other optical parameters.

Designed for focused target imaging, compact inspection, and low-distortion embedded vision applications.

Frequently Asked Questions

Q: What sensor size is this 16mm M12 lens designed for?
A: The lens is designed for 1/2.5″ image sensors and is specified for 5 Megapixel imaging applications.

Q: What is the field of view of the 16mm lens?
A: For the specified 16:9 configuration, the lens provides a 25° diagonal, 22° horizontal, and 12° vertical field of view.

Q: Is this lens a low distortion lens?
A: Yes. The specified optical distortion is less than 2.5%, making it suitable for applications that require controlled image geometry.

Q: Is the 16mm M12 lens suitable for wide-angle imaging?
A: No. With a 25° diagonal FOV, this lens is designed for relatively focused target coverage rather than wide-area or panoramic imaging.

Q: What is the advantage of the 16mm focal length?
A: The longer focal length provides a narrower field of view, allowing the camera to focus more closely on a defined target area and reduce unnecessary background coverage.

Q: What does the F1.6 aperture provide?
A: The F1.6 aperture provides good light-gathering capability, which can help maintain image brightness in indoor or variable-light imaging environments.

Q: What is the maximum image circle of this lens?
A: The maximum image circle is Φ8.0mm. Actual compatibility should be confirmed against the active imaging area of the selected sensor.

Q: Can this lens be used in a customized OEM vision system?
A: Yes. The M12×0.5 fixed focal configuration is suitable for compact OEM camera designs. Towin can evaluate requirements involving sensor format, focal length, field of view, mechanical dimensions, and application conditions through the Contact Towin page.
