Wide Angle Lens – CCL136022MPF

CCL136022MPF is 2.2mm High-Quality wide angle lens with Built-In Filter, F2.5 aperture M12/S-mount lens, 1/3.6″ Megapixel resolution CCTV lens.

For camera designs where the required coverage depends on sensor size and installation distance, the FOV Calculator can be used to estimate the viewing area before finalizing the lens selection.

2.2mm M12 Wide Angle Lens for Compact Vision Systems

This 2.2mm M12 wide angle lens combines a 135° diagonal field of view with megapixel resolution and controlled -18% TV distortion. Its compact M12 × 0.5 mount, F2.5 fixed aperture, manual focus, and 3G1P + IR cut optical construction make it a practical choice for embedded cameras that require broad scene coverage with better geometric control than an extreme fisheye lens.

With a 0.3m minimum object distance and 2.67mm back focal length, this fixed focal lens is particularly suitable for close-range monitoring, compact machine vision, automotive auxiliary cameras, and other space-constrained imaging devices.

Wide Angle Lens Core Product Highlights

• 135° Diagonal FOV: Provides broad scene coverage for compact camera installations.
• -18% TV Distortion: Offers more controlled geometric distortion than extreme fisheye optics.
• Megapixel Resolution: Supports detailed imaging for compact embedded vision applications.
• Manual Focus Design: Allows optical focus adjustment according to the actual installation distance.
• Compact M12 Mount: M12 × 0.5 mounting simplifies integration into small camera modules.

Applications & Compatible Devices

Core Application Scenes

This 2.2mm M12 low distortion lens is designed for applications that need a wide viewing area without relying on the extreme perspective of a conventional fisheye lens. The 105° horizontal and 80° vertical FOV provide broad coverage while the specified -18% TV distortion helps maintain a more controlled image geometry.

For smart security equipment, the lens is well suited to compact indoor cameras, entrance monitoring modules, small-area observation cameras, and embedded surveillance devices. Its wide horizontal coverage can reduce the number of cameras required to monitor a confined space, while manual focus allows installers to optimize image sharpness for the actual working distance.

In machine vision and embedded inspection systems, this lens can be used where the camera needs to observe a relatively large working area from a short distance rather than perform high-precision dimensional measurement. The megapixel optical specification provides more image detail than VGA-class optics, making it suitable for general scene recognition, object presence detection, and visual monitoring.

For automotive vision, the compact M12 configuration and wide field of view make the lens a candidate for auxiliary vehicle camera modules, parking-area observation, low-speed maneuvering assistance, and other close-range imaging applications. The controlled distortion characteristics can also be beneficial when the captured scene contains structural lines or objects that need to remain visually recognizable.

Beyond automotive and security applications, the lens can be integrated into compact robotic cameras and embedded AI vision devices that require a broad perspective within a limited mechanical envelope. Its 0.3m M.O.D. makes it particularly appropriate for relatively close working environments.

Frequently Asked Questions

Q: What type of lens is the 2.2mm M12 lens?

A: It is a fixed focal M12 wide angle lens with megapixel resolution, 135° diagonal FOV, and specified -18% TV distortion.

Q: What is the field of view of this M12 wide angle lens?

A: The lens provides a 135° diagonal FOV, 105° horizontal FOV, and 80° vertical FOV for broad scene coverage.

Q: What does the -18% TV distortion specification mean?

A: TV distortion describes the geometric deformation of straight lines toward the edges of the image. The specified -18% value indicates controlled but noticeable wide-angle distortion.

Q: Is this lens suitable for megapixel cameras?

A: Yes. The lens is specified with megapixel resolution and is designed for a 1/3.6″ image format.

Q: Can the focus be adjusted?

A: Yes. The lens uses a manual focus design, allowing the focus position to be adjusted according to the camera’s actual installation distance. The specified minimum object distance is 0.3m.

Q: What is the difference between this lens and an extreme fisheye lens?

A: This lens uses a 135° diagonal FOV with specified -18% TV distortion, providing broad coverage with more controlled geometry. An extreme fisheye lens generally prioritizes maximum viewing angle and may introduce substantially stronger image deformation.

Q: What applications are suitable for this lens?

A: Typical applications include compact security cameras, embedded vision systems, automotive auxiliary cameras, robotic vision modules, and close-range machine vision where wide coverage is important.

Q: How can I check whether the 2.2mm focal length provides sufficient coverage?

A: You can use the FOV Calculator to estimate image coverage based on the sensor and working distance. For projects where the focal length itself needs to be determined, the Focal Length Calculator can help with initial lens selection.
