Fisheye Lens – CCL118032MPF

CCL118032MPF-12MP wide-angle (154° diagonal) fisheye lens, 3.2mm F2.0, M12 mount lens

3.2mm 12MP M12 Fisheye Lens for Ultra-Wide-Angle Vision

This 3.2mm 12MP M12 fisheye lens is designed for ultra-wide-angle imaging where maximum scene coverage is required in a compact optical system. With a 154° diagonal FOV, 130° horizontal FOV, 90° vertical FOV, and 12MP resolution, it provides broad image coverage while maintaining high-resolution imaging performance. The M12×0.5 mount, F2.0 fixed aperture, manual focus, and 6.2mm BFL make it suitable for compact industrial cameras, embedded vision devices, and wide-area machine vision systems.

Product Core Highlights

• 154° Ultra-Wide Field of View — The 154° diagonal and 130° horizontal FOV capture a broad scene from a short 3.2mm focal length, reducing blind areas in wide-area imaging.
• 12MP High-Resolution Imaging — Supports detailed image acquisition for applications that require both extensive scene coverage and high pixel resolution.
• Compact M12×0.5 Mount — The M12 mount supports integration into compact cameras, embedded vision modules, and space-constrained optical assemblies.
• F2.0 Fixed Aperture — Provides a practical balance between light transmission and compact optical construction for continuous imaging applications.
• 8G + IRCF Optical Structure — The 8-element optical construction with an integrated IR cut filter supports visible-light imaging systems requiring controlled infrared transmission.

M12 Fisheye Lens Applications

Core Application Scenes

The combination of a 3.2mm focal length, 130° horizontal FOV, and 154° diagonal FOV makes this lens particularly suitable for applications where the camera must observe a large area from a short working distance. Its 12MP resolution helps retain useful image detail across the wide field of view, while the compact M12×0.5 interface simplifies integration into embedded imaging equipment.

For wide-area machine vision, the lens can be used when a conventional narrow-angle lens would require multiple cameras to cover the same scene. It is suitable for monitoring large working zones, equipment surroundings, robotic workspaces, and compact inspection platforms. TOWIN also provides dedicated Machine Vision optical solutions for industrial imaging systems.

The strong fisheye distortion of less than -58% is intentional and is part of the lens’s ultra-wide-angle imaging characteristics. It allows the optical system to achieve extensive scene coverage rather than geometrically preserving straight lines. For applications where geometric accuracy is more important than maximum coverage, a Low Distortion Lens would be a more appropriate optical choice.

Designed for ultra-wide-angle machine vision application, this lens is well suited to embedded cameras and industrial imaging systems that need a wide viewing area without using a large optical assembly.

Why Choose This 3.2mm 12MP Fisheye Lens?

A 3.2mm lens with a 130° horizontal FOV provides substantially wider scene coverage than conventional fixed-focal-length lenses. This can be particularly valuable when camera installation space is limited or when the system needs to observe a large area from a relatively short distance.

The 12MP resolution is another important advantage. Ultra-wide-angle imaging often requires a trade-off between coverage and image detail; the 12MP specification helps provide higher pixel density across the captured scene. The F2.0 aperture further supports practical light collection for indoor industrial and embedded imaging environments.

When selecting an ultra-wide-angle lens, however, distortion should be evaluated according to the application’s actual requirements. This lens is not designed as a low-distortion lens. Its <-58% distortion specification is closely associated with its fisheye optical design and extremely wide FOV.

Frequently Asked Questions

Q: What type of lens is this 3.2mm 12MP lens?
A: This is a fixed-focal-length M12 fisheye lens designed for ultra-wide-angle imaging. Its 154° diagonal FOV and 130° horizontal FOV provide extensive scene coverage.

Q: Is this lens suitable for machine vision?
A: Yes. Its 12MP resolution, ultra-wide FOV, compact M12 mount, and F2.0 aperture make it suitable for selected machine vision systems that prioritize broad scene coverage over low geometric distortion.

Q: Is this a low-distortion lens?
A: No. The lens has distortion below -58%, which is characteristic of a fisheye optical design. It should not be selected when accurate geometric reproduction or very low distortion is a primary requirement.

Q: What camera mount does this lens use?
A: The lens uses an M12×0.5 mount, making it compatible with many compact M12 camera modules and embedded vision systems.

Q: What is the field of view of the lens?
A: The lens provides a 154° diagonal FOV, 130° horizontal FOV, and 90° vertical FOV, delivering very broad scene coverage from a 3.2mm focal length.

Q: Does the lens support manual focusing?
A: Yes. The lens uses manual focus and a fixed zoom configuration, allowing the optical position to be adjusted during camera setup and then maintained during operation.

Q: What does the 8G+IRCF structure mean?
A: 8G indicates an eight-element optical construction, while IRCF indicates an integrated infrared cut filter. This should not be confused with an IR-corrected optical design.

Q: What applications are best suited to this fisheye lens?
A: It is suitable for wide-area machine vision, embedded cameras, robotic vision, compact monitoring systems, industrial observation, and other applications requiring very wide scene coverage from a compact camera module.

Lens Selection Resources

Choosing an ultra-wide-angle lens requires balancing focal length, sensor format, field of view, resolution, distortion, and mounting requirements. TOWIN’s Lens Selection Guide provides additional guidance for matching optical specifications with camera requirements.

You can also use the FOV Calculator to estimate image coverage based on lens focal length, sensor size, and working distance.
