Wide Angle Lens – CCL16018MP

CCL16018MP is 1.8mm Ultra-High-Quality wide angle lens, 1/6″ F2.5 S-Mount Lens with M12 Thread, 120° 2-Megapixel resolution CCTV HD lens.

1.8mm M12 120° Wide Angle Lens

This 1.8mm M12 wide angle lens is designed for compact imaging systems that require broad scene coverage with controlled wide-angle distortion. Featuring a 120° diagonal FOV, 2MP resolution, F2.5 fixed aperture, manual focus, and a compact 12.65mm total track length, it provides a practical optical solution for embedded cameras, compact monitoring equipment, robotics, and space-constrained vision devices.

M12 Wide Angle Lens Core Product Highlights

• 120° Ultra-Wide Field of View: Provides 120° diagonal, 92° horizontal, and 65° vertical coverage for capturing a broad scene with a compact camera.
• 1.8mm Short Focal Length: Delivers wide-area coverage while maintaining a practical optical configuration for miniature imaging systems.
• 2MP Resolution: Provides suitable image detail for compact monitoring, embedded vision, and general-purpose imaging applications.
• M12x0.5 Mount: Uses a standardized M12 interface for straightforward integration with compatible compact camera modules.
• Compact 12.65mm TTL: The short total track length supports optical integration where camera enclosure space is limited.

M12 Wide Angle Lens Applications

Core Application Scenes

The 1.8mm focal length and 120° diagonal FOV make this lens suitable for systems that need to observe a relatively large area from a compact camera position. Compared with more aggressive fisheye designs, its specified distortion of less than -13.5% provides a more controlled wide-angle imaging characteristic while still maintaining broad scene coverage.

Designed for compact wide-area imaging applications, this lens is suitable for embedded camera modules, compact monitoring devices, robotic vision systems, smart imaging equipment, and other applications where a wide viewing angle and short optical package are required.

The 1/6″ image format should be matched with the camera sensor during system design. Engineers can use TOWIN’s Sensor Guide to review sensor and lens compatibility before selecting the final optical configuration.

Compatible Device List

• Compact Camera Modules: The M12x0.5 mount and 12.65mm TTL make the lens suitable for small camera assemblies with limited internal optical space.
• Embedded Monitoring Devices: The 120° diagonal FOV provides broad scene coverage for compact monitoring equipment without requiring a large optical assembly.
• Robotic Vision Cameras: The wide viewing angle can help compact robots capture surrounding environmental information at relatively short distances.
• Smart Imaging Devices: The combination of 2MP resolution and wide-angle coverage is suitable for dedicated imaging products that prioritize scene coverage over long-distance magnification.
• Space-Constrained Vision Equipment: The short 12.65mm TTL supports integration into camera housings where conventional lenses may occupy too much optical depth.

For additional options with the same compact mounting concept, TOWIN’s M12 Lenses range includes lenses for different focal lengths, fields of view, and imaging requirements.

Field of view is strongly influenced by the relationship between focal length and sensor size. Before selecting a lens, engineers can use the FOV Calculator to estimate the required viewing coverage. The Focal Length Calculator can also help determine an appropriate focal length for a known working distance and target field of view.

Wide-Angle Distortion Considerations

This lens has a specified distortion of less than -13.5%. While this is significantly more controlled than many highly distorted fisheye designs, it should still be considered when the camera is used for dimensional measurement, geometric inspection, or applications where straight-line preservation is important.

For applications where distortion must be evaluated carefully, refer to TOWIN’s Distortion Guide to understand how optical distortion can influence the final image.

The manual-focus configuration also allows the focus position to be adjusted during camera assembly. This can be useful when the working distance differs between equipment designs. For optical integration and customized lens requirements, TOWIN’s Optical Design resources provide additional technical guidance.

Frequently Asked Questions

Q1: What type of lens is the 1.8mm M12 lens?

A: It is a fixed-focal-length M12 wide angle lens with a 1.8mm focal length, 120° diagonal FOV, and 2MP resolution. It is designed primarily for compact wide-area imaging applications.

Q2: What is the field of view of this 1.8mm lens?

A: The lens provides a 120° diagonal FOV, 92° horizontal FOV, and 65° vertical FOV on the specified 1/6″ image format.

Q3: What sensor size is this M12 lens designed for?

A: The specified image format is 1/6″. The camera sensor should be checked against this format before integration to ensure the required image coverage and avoid unwanted image cropping.

Q4: Is this a 2MP lens?

A: Yes. The specified resolution is 2 Megapixel, making it suitable for compact camera systems that require moderate image detail together with a wide field of view.

Q5: Is this lens a low-distortion lens?

A: The specified distortion is less than -13.5%. This is more controlled than many extreme fisheye designs, but the lens should not be classified as a conventional low-distortion lens for precision measurement applications without further optical testing.

Q6: Does the lens support manual focusing?

A: Yes. The lens uses manual focus, allowing the focus position to be adjusted during assembly according to the actual camera installation distance.

Q7: What mount does this lens use?

A: The lens uses an M12x0.5 mount, making it compatible with camera modules and imaging equipment designed for the corresponding M12 threaded interface.

Q8: Is this lens suitable for compact camera systems?

A: Yes. Its M12x0.5 mount, 12.65mm total track length, fixed aperture, and wide 120° diagonal FOV make it well suited to compact camera and embedded imaging designs.
