This 4.3mm M12 12MP fisheye lens is designed for high-resolution ultra-wide-angle imaging where a single camera needs to capture an exceptionally broad surrounding scene. Optimized for the IMX676 sensor, it provides a 180° field of view, F2.0 aperture, integrated IRCF, and M12 × 0.5 mounting for panoramic surveillance, robotics, embedded vision, and wide-area imaging systems.
This 4.3mm M12 fisheye lens is designed for high-resolution panoramic imaging where maximizing the visible scene is a primary requirement. Its 180° diagonal, horizontal, and vertical FOV allows a single camera to observe an exceptionally broad area, making it suitable for panoramic surveillance, environmental perception, and specialized spatial-awareness systems.
The 12MP resolution gives this lens a different positioning from conventional low-resolution fisheye camera modules. It can provide detailed image data across a very large scene, making it useful when operators or vision algorithms need both extensive coverage and high-resolution source imagery.
For panoramic security equipment, this configuration can be integrated into ceiling-mounted cameras, compact panoramic monitoring modules, and wide-area observation devices. A single optical module can cover a broad surrounding area, potentially reducing the need for multiple conventional cameras in applications where fisheye projection and image correction are supported by the camera system.
The lens is also suitable for robotics and autonomous vision systems that require broad environmental awareness. A 180° field of view can provide extensive near-field visual information around a robotic platform, complementing narrower lenses used for long-range object recognition.
For compact camera development, engineers can explore Towin’s M12 Lens solutions when evaluating M12-based ultra-wide optical configurations.
Designed for high-resolution panoramic surveillance, robotic perception, and ultra-wide embedded vision applications.
The defining feature of this lens is its 180° field of view in the diagonal, horizontal, and vertical directions when paired with the specified IMX676 sensor. This extreme coverage clearly places the lens in the fisheye lens category rather than conventional rectilinear wide-angle imaging.
The specified TV distortion of less than -29% is consistent with the optical projection required for such an extensive field of view. It should therefore be understood as part of the fisheye imaging characteristics rather than evaluated using the criteria normally applied to low-distortion industrial lenses.
For systems using software correction, panoramic stitching, or computer vision algorithms, the optical projection should be considered together with the camera ISP and image-processing pipeline.
Engineers can review the Distortion Guide to better understand how wide-angle and fisheye distortion affects image geometry and downstream image processing.
This lens is specifically specified with an IMX676 FOV configuration and supports a maximum image format of Φ7.0mm. The 12MP optical configuration makes sensor matching particularly important because the lens needs to provide adequate image quality across the sensor’s active area.
The 4.3mm focal length should therefore be evaluated together with the sensor format, image circle, camera housing, and desired field coverage rather than considered independently.
The Sensor Guide can help engineers evaluate sensor-format compatibility when developing a new camera module. For calculating image coverage and viewing geometry, the FOV Calculator can also be used during the optical selection process.
The M12 × 0.5 mount, 26.94mm TTL, and 0.2m M.O.D. make this lens suitable for compact camera-module integration. The fixed F2.0 aperture also delivers consistent optical configuration for applications that install the lens at a predetermined position.
The lens is specified With IRCF, providing an integrated IR-cut filter configuration for visible-light imaging systems. This streamlines optical integration for camera modules that require IR filtering within their imaging architecture.
For additional compact optical configurations, engineers can compare this product with Towin’s M12 Lenses range.
Q: Is this a fisheye lens?
A: Yes. The lens provides a 180° FOV in diagonal, horizontal, and vertical directions on the specified IMX676 configuration, making it an extreme fisheye imaging solution.
Q: What sensor is this 4.3mm lens designed for?
A: The specified FOV data is based on the Sony IMX676 sensor. The lens has a maximum image format of Φ7.0mm and is designed for 12MP imaging.
Q: What is the field of view of this M12 fisheye lens?
A: With the specified IMX676 configuration, the lens provides 180° diagonal, 180° horizontal, and 180° vertical FOV.
Q: Is this a low distortion lens?
A: No. The TV distortion is specified as less than -29%, which is associated with the extreme fisheye projection used to achieve the 180° field of view.
Q: Is this lens suitable for 12MP cameras?
A: Yes. The lens is specified as a 12MP optical configuration and is designed around the IMX676 sensor.
Q: What mount does this fisheye lens use?
A: The lens uses an M12 × 0.5 mount, which is suitable for compact embedded camera modules and miniature vision systems.
Q: Does this lens include an IRCF?
A: Yes. The specification states With IRCF, meaning the optical assembly includes an IR-cut filter configuration.
Q: What is the minimum object distance?
A: The specified M.O.D. is 0.2m, allowing the lens to capture relatively close-range scenes while maintaining its ultra-wide field of view.
