Fisheye Lens – CCL12802322MP

CCL12802322MP 2.3mm 4-Megapixel M12 fisheye lens with 172° FOV, 154° horizontal coverage and F2.2 aperture for panoramic security cameras.

2.3mm 4MP M12 Fisheye Lens

This 2.3mm 4MP M12 fisheye lens is designed for camera systems requiring an extremely wide field of view and maximum scene coverage. With a 172° diagonal FOV and 154° horizontal FOV when used with an IMX290 sensor, this lens provides an expansive viewing angle for surveillance, panoramic monitoring, smart security, and other applications where capturing a very large scene from a single camera is essential.

Featuring a 2.3mm focal length, M12X0.5 mount, F2.2 aperture, and compact 23.59mm total optical length, the lens is designed for wide-angle camera modules where fisheye projection and extensive scene coverage are more important than low geometric distortion.

Product Core Highlights

• 172° diagonal FOV — Provides exceptionally broad scene coverage with an IMX290 sensor configuration.
• 154° horizontal FOV — Captures an extremely wide horizontal viewing area from a single camera position.
• 4MP resolution — Provides detailed imaging for wide-area monitoring applications.
• 2.3mm fisheye optical design — Designed for applications requiring maximum field coverage rather than low distortion.
• M12X0.5 compact mount — Supports integration into compact camera modules and embedded imaging devices.

M12 Fisheye Lens Applications

The 2.3mm 4MP M12 fisheye lens is designed for applications where maximum field of view is the primary optical requirement. Its 154° horizontal FOV can cover a very broad scene from a single camera position, making it suitable for panoramic observation and wide-area monitoring.

Typical applications include panoramic security cameras, indoor surveillance, room monitoring, retail observation, entrance monitoring, smart security devices, and embedded wide-angle camera systems. The fisheye optical configuration can also be useful when a single camera needs to observe a large surrounding area while accepting significant geometric distortion as part of the imaging design.

The 0.3m minimum object distance makes the lens suitable for relatively close-range wide-area observation, while the M12X0.5 mounting interface supports compact camera module integration. The IMX290 reference provides a 172° diagonal and 154° horizontal FOV configuration for systems using that sensor.

Compatible devices: IMX290-based camera modules, panoramic security cameras, indoor surveillance cameras, smart security cameras, retail monitoring devices, room-monitoring systems, embedded fisheye cameras, and other M12 wide-area imaging systems.

Because fisheye lenses intentionally introduce substantial geometric distortion to achieve an extremely wide field of view, the Distortion Guide can help when evaluating whether this optical configuration is appropriate for your imaging system. You can also use the FOV Calculator to compare different focal lengths and sensor configurations.

Frequently Asked Questions

Q: What type of lens is the 2.3mm 4MP lens?
A: It is an M12 fisheye lens with a 2.3mm focal length and an extremely wide field of view, reaching 172° diagonal and 154° horizontal FOV with an IMX290 sensor.

Q: What sensor is referenced for the 172° FOV specification?
A: The listed FOV is specified for the Sony IMX290 sensor configuration. The actual FOV may vary with the sensor format and active imaging area used in the final camera.

Q: Why does this fisheye lens have such high distortion?
A: Extremely wide-angle fisheye designs use a projection that allows much larger scene coverage than conventional wide-angle lenses. The resulting geometric distortion is an intentional characteristic of the optical design rather than a defect.

Q: Is this lens suitable for low-distortion imaging?
A: No. With optical distortion specified below -90%, this lens is intended for fisheye and ultra-wide scene coverage applications rather than precision low-distortion imaging.

Q: What applications are suitable for this M12 fisheye lens?
A: It is suitable for panoramic surveillance, indoor monitoring, room observation, retail monitoring, entrance monitoring, smart security cameras, and other applications requiring extremely wide scene coverage.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.3m, making it suitable for relatively close-range wide-area observation.

Q: What does MAX Φ6mm mean for this lens?
A: MAX Φ6mm indicates the specified maximum image format or image-circle-related optical coverage. Final compatibility should be verified against the camera sensor’s active area and optical mechanical design.

Q: Can TOWIN customize an M12 fisheye lens?
A: TOWIN can evaluate customized requirements such as focal length, FOV, sensor compatibility, mounting configuration, and other optical parameters according to the target camera system.
