Fisheye Lens – CCL1170185MP

12MP 1.85mm 185° M12 Fisheye Lens

This 1.85mm M12 fisheye lens delivers an ultra-wide 185° field of view with 12MP resolution, making it suitable for compact imaging devices that need maximum scene coverage from a very small installation space. With IR correction, F2.0 aperture, and a compact 34.49mm TTL, this fixed focal lens is designed for wide-area monitoring, smart cameras, robotics, and other embedded vision applications.

As part of our M12 Lenses portfolio, this lens combines an M12×0.5 mount with an ultra-wide fisheye optical design for applications where conventional wide angle lenses cannot provide sufficient coverage.

The 1.85mm focal length and 185° field of view give this Fisheye Lenses an extremely broad viewing range. The optical distortion is intentionally designed for a fisheye configuration rather than low-distortion imaging, allowing the lens to capture a much larger scene within a compact camera system.

For projects that require a different combination of focal length, sensor format, or field of view, our Lens Selection Guide can help engineers identify the appropriate optical configuration.

M12 Fisheye Lens Core Highlights

• 185° ultra-wide field of view for maximum scene coverage
• 12MP resolution for detailed wide-area imaging
• 1.85mm fixed focal length for compact embedded camera designs
• IR corrected optical design for improved visible/IR imaging compatibility
• M12×0.5 mount and 34.49mm TTL for space-constrained camera modules

The combination of ultra-wide coverage and high resolution makes this M12 Wide Angle Lens particularly useful when the camera must observe a large area without requiring mechanical pan or multiple conventional cameras.

M12 Fisheye Lens Applications

Wide-Area Smart Camera Systems

The 185° field of view makes this lens suitable for compact smart cameras that need to monitor almost the entire surrounding environment from a single installation point. It can be used in indoor monitoring devices, smart home cameras, compact security modules, and embedded IoT vision systems where installation space is limited.

The short 1.85mm focal length allows the camera to capture a very large scene at close range, while the 0.1m minimum object distance supports applications where important objects may be positioned relatively close to the camera.

Smart Doorbells and Indoor Security Devices

This lens is particularly suitable for smart video doorbells, compact indoor security cameras, room monitoring devices, and other consumer or commercial camera modules requiring an extremely wide viewing angle. The 185° FOV can reduce blind spots around the installation area and provide broader coverage than conventional wide-angle lenses.

Its compact M12×0.5 interface also makes integration easier for small camera housings where a larger C-Mount or CS-Mount lens would be impractical.

For security-oriented optical designs, TOWIN also provides dedicated Smart Security lens solutions for different camera configurations and imaging requirements.

Robotics and Embedded Vision

In mobile robots and compact robotic platforms, the lens can provide broad environmental awareness for navigation, obstacle observation, and situational monitoring. The 185° coverage is especially valuable when the camera needs to observe a large surrounding area without adding additional camera modules.

For more demanding robotic imaging systems requiring higher optical control and lower distortion, engineers can also review our Robotics Vision solutions to select a lens according to sensor size, FOV, resolution, and distortion requirements.

Panoramic and Omnidirectional Imaging

The extremely wide 185° FOV makes this lens a strong candidate for panoramic and near-omnidirectional imaging systems. It can be integrated into compact cameras used for room observation, equipment monitoring, interactive devices, and spatial awareness applications.

Because fisheye lenses intentionally introduce substantial optical distortion to achieve ultra-wide coverage, image-processing or fisheye correction software can be applied when a rectilinear output image is required.

Compatible Devices

This 12MP M12 Fisheye Lens can be integrated with a range of compact camera platforms and embedded imaging devices, including:

• Smart video doorbells
• Compact security cameras
• Indoor monitoring cameras
• Smart home IoT cameras
• Robotic vision modules
• Mobile robot cameras
• Panoramic camera modules
• Embedded vision systems
• Wide-area monitoring devices
• Compact industrial observation cameras

The lens is designed for 1/1.7″ sensor-format applications and uses an M12×0.5 mount. For projects where sensor size, focal length, and required FOV need to be matched precisely, TOWIN’s FOV Calculator can be used during the lens selection process.

Frequently Asked Questions

Q: What type of lens is this product?
A: This is a 1.85mm fixed focal M12 fisheye lens with a 185° field of view, 12MP resolution, and IR-corrected optical design.

Q: Why does this lens have optical distortion below -97%?
A: The high distortion is an intentional characteristic of the fisheye optical design. It enables the lens to achieve an extremely wide 185° field of view that would not be possible with a conventional low-distortion wide-angle lens.

Q: Is this a low-distortion lens?
A: No. This lens is optimized for ultra-wide scene coverage rather than geometric accuracy. Applications requiring straight-line imaging should consider a dedicated Low Distortion Lens instead.

Q: What sensor size is this M12 fisheye lens designed for?
A: The lens is specified for a 1/1.7″ sensor format and supports 12MP resolution. The actual image performance should be evaluated together with the selected CMOS sensor and camera module.

Q: What is the field of view of this 1.85mm lens?
A: The specified field of view is 185° diagonal, 185° horizontal, and 185° vertical, providing extremely broad scene coverage.

Q: Is this lens suitable for infrared imaging?
A: Yes. The lens is IR corrected, making it suitable for camera systems that require improved optical performance across visible and infrared wavelengths, depending on the specific sensor and IR illumination configuration.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.1m, allowing the lens to capture objects at relatively close distances while maintaining its ultra-wide viewing capability.

Q: Can TOWIN customize this M12 fisheye lens?
A: TOWIN can evaluate customized optical requirements such as focal length, sensor format, field of view, distortion characteristics, mechanical dimensions, and other optical parameters. For a project-specific requirement, please contact TOWIN with your camera and application specifications.
