Fisheye Lens – CCL118018MPF

CCL118018MPF Fisheye HD lens 1/1.8″ Φ5 180° M12 mount lens F2.5 for 3MP 360 AR panoramic camera

1.8mm Megapixel M12 Fisheye Lens – 180° FOV

This 1.8mm M12 fisheye lens is designed for compact imaging systems that require an extremely wide 180° field of view. With a 1/1.8″ image format, megapixel-level resolution, F2.5 fixed aperture, and M12X0.5 mount, the lens provides broad scene coverage for embedded cameras and space-constrained imaging devices. Its 180° diagonal, horizontal, and vertical FOV enables near-panoramic scene capture from a single camera, while the 6G optical construction with an integrated IR cut filter supports practical visible-light imaging. The compact 15.17mm TTL and 3.20mm BFL design makes this M12 fisheye lens suitable for applications where maximum viewing coverage is more important than geometric image correction.

• 6G + IR Cut Filter: Multi-element optical construction with an integrated IR cut filter for visible-light imaging.

Product Applications & Compatible Devices

Panoramic and 360°-Style Monitoring

The 180° FOV makes this lens suitable for applications that need to capture a very large area from a single camera position. It can be integrated into panoramic monitoring cameras, compact surveillance devices, ceiling-mounted cameras, and other wide-area monitoring systems where reducing blind spots is a priority.

Compatible devices: panoramic cameras, compact security cameras, ceiling cameras, embedded monitoring cameras.

Smart Home and IoT Cameras

Its M12X0.5 mount, short 1.8mm focal length, and compact optical structure make the lens suitable for embedded smart-camera designs. The extremely wide viewing angle can help cover rooms, entrances, corridors, and other confined spaces without requiring multiple cameras.

Compatible devices: smart home cameras, IoT cameras, indoor monitoring devices, compact network cameras.

Robotics and Embedded Vision

The 180° field of view can be useful for mobile or compact robotic platforms that need broad environmental awareness. Rather than focusing on long-distance detail, the fisheye configuration prioritizes wide scene capture around the camera.

Compatible devices: mobile robots, service robots, embedded vision modules, autonomous monitoring devices.

Wide-Area Inspection and Observation

The lens can also be considered for compact inspection or observation systems where a large field of view is more important than maintaining rectilinear geometry. The pronounced optical distortion is characteristic of the fisheye design and can be addressed through image processing when required.

Compatible devices: compact inspection cameras, observation cameras, embedded imaging modules.

How to Select This 180° M12 Fisheye Lens

When selecting an ultra-wide-angle lens, the camera sensor, required field of view, mechanical interface, and image-processing capability should be evaluated together. This lens is particularly suitable when the design objective is maximum scene coverage rather than low geometric distortion.

For sensor compatibility, refer to the Sensor Guide. For field-of-view planning, the FOV Calculator can help estimate the relationship between sensor format, focal length, and viewing coverage.

The 1.8mm M12 fisheye lens is therefore best suited to compact camera systems where a 180° viewing angle is a primary requirement.

Frequently Asked Questions

Q1: What type of lens is this?
A: This is a 1.8mm fixed focal M12 fisheye lens with a 180° diagonal, horizontal, and vertical field of view.

Q2: What sensor format is this lens designed for?
A: The lens is specified for a 1/1.8″ image format and a Φ5.0 image circle specification.

Q3: Does this lens provide a 180° field of view?
A: Yes. The specified FOV is 180° in diagonal, horizontal, and vertical directions at Φ5.0.

Q4: Why is the optical distortion higher than that of a conventional wide-angle lens?
A: The <-87.5% optical distortion is a characteristic of the fisheye optical design, which enables extremely wide 180° scene coverage.

Q5: Is this an M12 lens?
A: Yes. The lens uses an M12X0.5 mount, making it suitable for compact camera modules and embedded imaging systems designed around an M12 interface.

Q6: Is the lens IR corrected?
A: The supplied specification lists an integrated IR cut filter rather than an IR-corrected optical design. Therefore, it should not be classified as an IR Corrected Lens based on the available specifications.

Q7: Is the focal length adjustable?
A: No. The focal length is fixed at 1.8mm, and the specification also identifies the zoom configuration as fixed.

Q8: What is the back focal length of this lens?
A: The specified B.F.L. is 3.20mm, while the total optical length (TTL) is specified as 15.17mm.
