Low Distortion Lens – CCL118040MPFR

CCL118040MPFR 4mm 6MP M12 wide angle Low Distortion Lens with 98° FOV

4mm 6MP M12 Low Distortion Wide Angle Lens for 1/1.8″ Sensors

This 4.0mm M12 lens is designed for high-resolution imaging systems that require a wide field of view, low distortion, and a compact mechanical design. Supporting 1/1.8″ image sensors and up to 6MP resolution, it delivers a 98° diagonal, 85° horizontal, and 70° vertical FOV while maintaining distortion below -0.4%. Its fixed F2.8 aperture, 21.98mm TTL, and Φ14 × 18.7mm dimensions make it suitable for compact industrial cameras, embedded vision devices, inspection systems, and smart imaging equipment.

Product Core Highlights

• 6MP high-resolution imaging — Supports detailed image capture for advanced vision and monitoring systems.
• Wide 98° diagonal FOV — Provides broad scene coverage from a compact 4.0mm focal length.
• Low distortion below -0.4% — Helps preserve object shape and positional accuracy in vision applications.
• 1/1.8″ sensor compatibility — Provides a larger image format than many compact M12 lenses and supports high-resolution imaging.
• Compact M12 optical design — Φ14 × 18.7mm dimensions and M12 × 0.5 mounting simplify integration into space-constrained camera systems.

Wide-Angle and Low-Distortion Imaging Performance

The combination of a 4.0mm focal length and 85° horizontal FOV allows this lens to capture a broad scene without using an extreme fisheye optical design. With distortion specified below -0.4%, the lens is particularly useful where image geometry and object proportions need to remain relatively stable.

The 1/1.8″ image format and 6MP resolution also make this lens suitable for systems that require more image detail while maintaining a compact M12 interface. For engineers evaluating the relationship between sensor format and lens selection, TOWIN’s Sensor Guide provides additional technical guidance.

M12 Low Distortion Lens Applications

Compact Machine Vision and Inspection

The wide field of view allows cameras to cover larger inspection areas from a relatively short working distance, while low distortion helps maintain more consistent object geometry. This makes the lens suitable for compact inspection cameras, component checking, dimensional observation, and automated visual inspection equipment.

Embedded Industrial Vision Systems

With a compact Φ14 × 18.7mm optical structure and M12 × 0.5 mount, this lens can be integrated into embedded vision equipment where installation space is limited. The 6MP resolution provides sufficient detail for object detection, positioning, classification, and general-purpose industrial imaging.

Smart Monitoring and Object Recognition

The 98° diagonal FOV provides broad scene coverage for cameras used in indoor monitoring, equipment observation, access-area monitoring, and object recognition. The low-distortion optical design helps reduce geometric deformation compared with conventional wide-angle lenses.

Robotics and Automation Cameras

The combination of wide coverage, compact size, and low distortion can benefit robotic vision systems that need to observe work areas, detect objects, or monitor equipment within a relatively confined installation space.

Compatible Devices

This lens is compatible with imaging devices using 1/1.8″ sensors and an M12 × 0.5 lens interface, including compact industrial cameras, embedded vision cameras, smart monitoring cameras, robotic vision modules, and customized machine vision equipment.

Frequently Asked Questions

Q: What type of lens is this?
A: This is a 4.0mm M12 fixed focal lens with a wide 98° diagonal FOV, 6MP resolution, and distortion below -0.4%, designed for compact high-resolution imaging systems.

Q: What sensor size is compatible with this lens?
A: The lens is designed for 1/1.8″ image sensors and supports up to 6MP resolution according to the supplied optical specifications.

Q: Is this a wide-angle lens?
A: Yes. With a 98° diagonal, 85° horizontal, and 70° vertical FOV, the lens provides wide-angle coverage while avoiding the extreme distortion normally associated with fisheye optics.

Q: How low is the distortion of this M12 lens?
A: The specified distortion is below -0.4%, making it suitable for imaging applications where maintaining relatively accurate image geometry is important.

Q: Is this lens IR corrected?
A: No. The specification includes an IR‑cut filter, distinct from IR‑corrected optics. An IR‑cut filter blocks unwanted infrared light, whereas IR correction is an optical design that preserves focus across visible and infrared wavelengths.

Q: What mount does this lens use?
A: The lens uses an M12 × 0.5 mount, making it suitable for compact camera modules and embedded imaging systems designed for M12 lenses.

Q: What applications can use this 4mm M12 lens?
A: Typical applications include compact machine vision, industrial inspection, embedded cameras and robotics vision. It also covers smart monitoring, object recognition and other imaging systems requiring a wide FOV with low distortion.

Q: Can TOWIN customize this lens for a specific imaging system?
A: TOWIN can evaluate optical requirements such as sensor size, focal length, FOV, resolution, distortion, aperture, mechanical dimensions, and mounting requirements for customized optical solutions. Contact TOWIN to discuss your project requirements.
