Low Distortion Lens – CCL118040MPFR

CCL118040MPFR is Low distortion Wide-angle 6-Megapixel M12 lens with Built-In IR Filter, 1/1.8″ 98° F2.8 aperture lens for security surveillance.

M12 4mm 6MP Low Distortion Wide Angle Lens

This 4mm M12 low distortion wide angle lens is designed for 1/1.8″ sensors requiring a broad field of view without the strong geometric distortion associated with fisheye optics. With 6MP resolution, 98° diagonal FOV, and distortion below 0.4%, it provides a compact optical solution for machine vision, industrial imaging, and embedded vision systems.

The combination of a 1/1.8″ image format and 4mm focal length provides a wide viewing area while maintaining controlled optical distortion. Engineers can also use the Sensor Guide when matching the lens to a compatible CMOS sensor.

M12 4mm Low Distortion Lens Applications

Core Application Scenes

This 1/1.8″ M12 wide angle lens is designed for vision systems that need to capture a relatively large scene while maintaining accurate image geometry. Its 98° diagonal field of view allows a single camera to cover a broad area, while the distortion below 0.4% helps reduce the curved-line effect commonly associated with conventional wide-angle optics.

The lens is particularly suitable for compact machine vision and embedded industrial cameras installed where the camera cannot be positioned far from the target area. The 4mm focal length provides broad scene coverage without requiring a fisheye optical design, making it useful for equipment monitoring, visual inspection, robotic sensing, and other fixed-camera applications.

With a 0.4m minimum object distance, the lens can also be used for relatively close-range imaging where a wide perspective is required. The F2.8 fixed aperture provides a stable optical configuration, while the 21.8mm T.T.L. allows integration into compact camera assemblies with defined mechanical depth.

For projects where the required viewing area depends on sensor dimensions and working distance, the FOV Calculator can help engineers estimate the required optical configuration before final lens selection.

Frequently Asked Questions

Q: What sensor size is this M12 lens designed for?
A: This lens is designed for 1/1.8″ image formats and supports up to 6MP resolution on compatible CMOS sensors.

Q: What is the field of view of this 4mm M12 lens?
A: The lens provides a 98° diagonal FOV, 85° horizontal FOV, and 70° vertical FOV on the specified image format.

Q: Is this M12 lens a low distortion lens?
A: Yes. Its specified distortion is below -0.4%, providing highly controlled image geometry for applications that require a wide viewing area without significant barrel distortion.

Q: Is this lens a fisheye lens?
A: No. Despite its 98° diagonal field of view, the lens is designed as a low distortion wide angle lens. Its distortion below 0.4% is significantly different from the strong geometric distortion normally associated with fisheye optics.

Q: Is this 4mm lens suitable for machine vision?
A: Yes. Its 6MP resolution, wide FOV, low distortion, and M12 × 0.5 mounting configuration make it suitable for compact machine vision and embedded industrial imaging systems.

Q: What is the minimum object distance of this M12 lens?
A: The specified M.O.D. is 0.4m, making the lens suitable for relatively close-range wide-angle imaging applications.

Q: Does the lens have IR correction?
A: The optical structure is specified as 2G2P + IRCF. IRCF refers to an IR Cut Filter and should not be interpreted as IR correction. The lens is therefore primarily configured for visible-light imaging.

Q: Can TOWIN customize this M12 wide angle lens?
A: TOWIN can evaluate OEM optical and mechanical requirements, including sensor compatibility, mounting specifications, optical performance, and housing configurations. For project-specific requirements, contact the TOWIN engineering team.
