Wide Angle Lens – CCL13018

CCL13018 is Wide-angle CCTV lens 1/3″ Φ14×13.6 M12/S-Mount Lenses with Low F-number (Fast Lenses) 165° F2.0 security surveillance.

1.8mm M12 165° Wide Angle Lens

This 1.8mm M12 Wide Angle lens is designed for compact imaging systems that require an extremely wide field of view in a small optical package. With a 165° diagonal FOV, 1/3″ image format, F2.0 aperture, and 18.7mm TTL, it provides broad scene coverage for embedded cameras, surveillance, robotics, and spatial awareness applications.

Its M12x0.5 mount and Φ14 × 13.6mm compact dimensions make it suitable for space-constrained camera designs where a conventional wide-angle lens may not provide sufficient coverage. For more information about compact M12 optical solutions, explore our M12 Lenses.

Product Core Highlights

• 165° Ultra-Wide FOV – Captures a very broad scene from a compact camera position, reducing blind spots.
• 1.8mm Short Focal Length – Provides extensive coverage for close-range and spatial awareness imaging.
• Compact M12 Mount – M12 × 0.5 mounting supports small embedded camera designs and space-limited systems.
• F2.0 Aperture – Provides a practical balance between light collection and compact optical construction.
• Compact 18.7mm TTL – Helps simplify integration into miniature camera housings and embedded imaging devices.

Wide Angle Lens Applications

The combination of a 1.8mm focal length and 165° diagonal field of view makes this lens particularly suitable when maximum scene coverage is more important than geometric image accuracy. The -55% distortion is characteristic of an ultra-wide/fisheye optical design and can be useful for applications where capturing the surrounding environment is the primary requirement.

Core Application Scenes

Designed for ultra-wide spatial awareness applications, this lens can capture a large area from a short camera-to-subject distance. It is suitable for applications such as:

• Compact security and surveillance cameras
• Indoor panoramic monitoring
• Robotics and mobile robot vision
• Embedded spatial awareness cameras
• Smart home and IoT cameras
• Short-range environment monitoring
• Compact panoramic imaging systems
• Obstacle and surrounding-area observation

For robotic platforms requiring broad environmental visibility, this lens can complement TOWIN’s Robotics Vision solutions where wide scene coverage is needed within a compact camera module.

Compatible Devices

Compact Embedded Cameras
The M12 × 0.5 mount and Φ14mm optical diameter make the lens suitable for compact camera modules where installation space is limited.

Robotics Cameras
The 165° FOV allows a robot-mounted camera to observe a large surrounding area without requiring multiple conventional lenses.

Security Cameras
The ultra-wide optical design can help reduce blind areas in indoor monitoring environments, particularly where the camera is installed close to the monitored area.

IoT and Smart Devices
The compact optical structure can be integrated into small smart devices requiring broad environmental visibility.

For applications where image distortion needs to be controlled rather than maximizing coverage, TOWIN also offers dedicated Low Distortion Lenses.

Why Choose This M12 Wide Angle Lens?

A conventional wide-angle lens may not provide enough coverage when the camera needs to observe a very large area from a short distance. This 1.8mm lens addresses that requirement with a 165° diagonal field of view while maintaining a compact M12 form factor.

Its -55% distortion should be considered a design characteristic rather than a defect. For panoramic and spatial-awareness applications, the priority is often maximizing scene coverage. If accurate object geometry, measurement, or machine vision inspection is required, lens selection should instead consider distortion, sensor size, resolution, and working distance together.

TOWIN provides additional guidance through its Lens Selection Guide and FOV Calculator.

Frequently Asked Questions

Q: What is the field of view of this 1.8mm M12 lens?
A: This lens provides a 165° diagonal field of view, making it suitable for ultra-wide and Wide Angle imaging applications where broad scene coverage is required.

Q: Is this a low-distortion lens?
A: No. The lens has approximately -55% distortion and is designed as an ultra-wide/fisheye optical solution rather than a low-distortion lens.

Q: What sensor size is this M12 lens designed for?
A: The lens suits 1/3″ image formats and works well with compact cameras that use compatible 1/3″ sensors.

Q: What applications are suitable for this 1.8mm lens?
A: Typical applications include compact surveillance, robotics, embedded cameras, indoor monitoring, IoT devices, and spatial awareness systems that benefit from a very wide field of view.

Q: Why is the distortion relatively high?
A: A 165° field of view requires an ultra-wide optical design, which naturally introduces significant geometric distortion. This trade-off allows the lens to capture a much larger scene than conventional lenses.

Q: Is the lens suitable for machine vision inspection?
A: It can be used for machine vision systems when broad scene coverage is more important than geometric accuracy. For precision inspection and measurement, a lower-distortion lens is generally more appropriate.

Q: What does the M12 × 0.5 mount mean?
A: M12 × 0.5 identifies the lens mounting thread, with a nominal 12mm thread diameter and 0.5mm pitch. It is commonly used for compact embedded camera modules.
