Low Distortion Lens – S08611804856F

S08611804856F is Low-distortion 1/1.8″ M12-mount 6-Megapixel CCTV lens with Built-In IR Filter, 60° diagonal FOV and F5.6 aperture for security surveillance.

8.6mm M12 Low Distortion Lens

This 8.6mm 6MP M12 low distortion lens is designed for compact high-resolution imaging systems that require controlled geometric distortion, stable image quality, and a well-defined field of view. Supporting a 1/1.8″ image format with distortion below -1%, it provides a practical optical solution for embedded machine vision and precision imaging applications.

With an M12×0.5 mount, 8.6mm fixed focal length, F5.6 fixed aperture, and 5G+IRCF optical construction, this compact lens also features a relative illumination of more than 60%, helping maintain useful image brightness toward the image periphery.

Product Highlights at a Glance

8.6mm M12 Low Distortion Lens Applications

Core Application Scenes

This 8.6mm M12 low distortion lens is designed for compact imaging systems where the camera needs a defined viewing area and controlled geometric representation rather than extreme wide-angle coverage. Its 48° horizontal FOV provides a balanced view for targets located at moderate working distances, while the distortion below -1% helps reduce image deformation.

The lens is particularly suitable for compact machine vision modules, embedded inspection cameras, intelligent equipment monitoring, code recognition, and precision visual analysis systems. The 6MP resolution provides sufficient image detail for many inspection and recognition tasks, while the low-distortion optical design helps maintain consistent object geometry across the captured scene.

Its >60% relative illumination is another useful characteristic for applications where image quality near the edge of the sensor matters. By maintaining useful illumination across the image field, the lens can provide more consistent visual information for image-processing algorithms and inspection systems.

The compact 12mm TTL is advantageous when the camera module has strict mechanical space limitations. Combined with the M12×0.5 mounting interface and 2.8mm back focal length, the lens can be integrated into compact embedded camera architectures without requiring the physical dimensions of a conventional larger-format industrial lens.

For optical system planning, engineers should evaluate sensor format, working distance, target dimensions, and field of view together. Towin’s Lens Selection Guide provides practical guidance for selecting an appropriate lens configuration, while the FOV Calculator can be used to estimate scene coverage.

Frequently Asked Questions

Q: What type of lens is this 8.6mm M12 lens?
A: It is an 8.6mm fixed focal M12 lens designed for 1/1.8″ image formats. With 6MP resolution and distortion below -1%, it is suitable for compact low-distortion machine vision and embedded imaging systems.

Q: What sensor size is this lens designed for?
A: The supplied FOV specifications are based on a 1/1.8″ image format, with a maximum image circle of Φ9.0mm.

Q: How much distortion does this M12 lens have?
A: The specified distortion is below -1%. This controlled distortion helps reduce geometric deformation and is useful for applications that require consistent representation of objects within the image.

Q: What is the field of view of the 8.6mm lens?
A: The lens provides a 60° diagonal FOV, 48° horizontal FOV, and 36° vertical FOV when used with the specified 1/1.8″ image format.

Q: What does the relative illumination of >60% mean?
A: Relative illumination describes the amount of light reaching different areas of the image compared with the center. A specification above 60% indicates that the lens is designed to retain useful illumination toward the image periphery.

Q: Is this lens suitable for machine vision applications?
A: Yes. Its 6MP resolution, 1/1.8″ image format, < -1% distortion, fixed focal length, and compact M12×0.5 mount make it suitable for various embedded machine vision and inspection systems.

Q: What is the minimum object distance of this lens?
A: The minimum object distance is 0.2m. This allows the lens to be used for relatively close-range imaging when the camera is correctly positioned and focused.

Q: Why is the 12mm TTL useful for embedded camera design?
A: A 12mm total track length provides a compact optical configuration, which can be beneficial when integrating the lens into small camera housings or embedded vision modules with limited space.
