Fisheye Lens – S7418022

S7418022 is 2.5mm Fisheye 8-Megapixel lens with 1/1.8″ M12/S-Mount 180° field of view, F2.2 Aperture, Suitable for security surveillance.

2.5mm 8MP M12 Fisheye Lens

This 2.5mm 8MP M12 fisheye lens is designed for ultra-wide imaging systems that require a 180° field of view from a compact camera module. With a 1/1.8″ image format, F2.2 aperture, and M12 × 0.5 mount, it provides broad environmental coverage for panoramic imaging, robotics vision, AI perception, and specialized machine vision systems.

The combination of a 2.5mm focal length and 180° field of view makes this lens suitable for applications where extremely broad scene coverage is required. Engineers can use the FOV Calculator to evaluate the expected image coverage and determine the appropriate optical configuration for their camera system.

2.5mm M12 Fisheye Lens Applications

Core Application Scenes

This 8MP M12 fisheye lens is intended for applications where a conventional wide-angle lens cannot provide enough scene coverage. Its 180° diagonal and horizontal FOV allow a single camera to capture a very broad surrounding area, making it useful for panoramic and hemispherical imaging systems.

For robotics vision, the extremely wide perspective can provide broad environmental awareness around a mobile or stationary robotic platform. Rather than concentrating the camera view on a narrow forward-facing region, the fisheye optical design can capture a much larger portion of the surrounding environment for subsequent image processing and perception algorithms.

In panoramic imaging and spatial monitoring, the 180° field of view can reduce blind areas around the camera. This makes the lens suitable for compact panoramic camera modules, indoor spatial-awareness devices, and other systems where maximizing scene coverage from one optical position is a primary requirement.

The 0.2m minimum object distance also allows the lens to be used in relatively close-range environments where the camera needs to observe both nearby objects and a broad surrounding scene. Its 1/1.8″ image format and 8MP resolution make it appropriate for higher-resolution camera platforms based on sensors such as the IMX678.

For engineers evaluating the relationship between sensor size, focal length, and field of view, the Sensor Guide provides additional information for optical system selection.

Frequently Asked Questions

Q: Is this a fisheye lens?
A: Yes. The 180° diagonal and horizontal field of view indicate a fisheye optical design intended for extremely wide-angle imaging.

Q: What is the focal length of this M12 fisheye lens?
A: The lens has a fixed 2.5mm focal length.

Q: What is the field of view of this 2.5mm lens?
A: When used with the specified IMX678 configuration, the FOV is 180° diagonal, 180° horizontal, and 107° vertical.

Q: What resolution does this fisheye lens support?
A: The lens is specified for 8MP resolution and is designed around a 1/1.8″ image format.

Q: Why does this lens have very high distortion?
A: Fisheye lenses intentionally use strong optical projection to achieve an extremely wide field of view. The specified distortion of less than -95% is therefore fundamentally different from the controlled distortion specification of a conventional low-distortion lens.

Q: Is this lens a low distortion lens?
A: No. This product should not be classified as a Low Distortion Lens. Its optical design prioritizes extremely wide scene coverage and uses strong fisheye distortion to achieve the 180° field of view.

Q: What sensor is this M12 fisheye lens designed for?
A: The provided FOV specification is based on the Sony IMX678 configuration, with a 1/1.8″ image format.

Q: Does this lens include an IR cut filter?
A: No. The provided specification states Without IRCF, so the lens does not include an integrated IR cut filter in this configuration.
