2.1mm M12 Ultra Wide Angle Lens Applications

Core Application Scenes

This 2.1mm M12 ultra wide angle lens is designed for vision systems where the camera needs to capture a large area from a relatively short installation distance. Its 110° horizontal and 90° vertical FOV allow a single compact camera module to cover a broad scene, reducing blind areas in applications where camera placement is constrained.

For embedded machine vision, the lens can be used where the target occupies a large area around a compact camera, such as object presence detection, access-area monitoring, equipment status recognition, and wide-area visual inspection. The 0.1m minimum object distance is particularly useful for applications where the camera is installed close to the monitored scene.

The BPF850 filter adds another important characteristic to this lens. Rather than being treated simply as a conventional visible-light wide-angle lens, this configuration can be considered for imaging systems designed around approximately 850nm wavelength-band illumination. This can be useful in embedded sensing and machine vision equipment using controlled near-infrared illumination.

For applications involving machine perception, the combination of wide FOV and compact M12 mounting is also suitable for robotic and AI vision devices that need to observe a large operating area without using a mechanically larger lens assembly.

Frequently Asked Questions

Q: What sensor size is this 2.1mm M12 lens designed for?
A: This lens targets 1/2.5″ image sensors and delivers 5MP resolution per published specifications.

Q: What is the field of view of this M12 wide angle lens?
A: It provides a 124° diagonal, 110° horizontal, and 90° vertical field of view, making it suitable for applications requiring broad scene coverage.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a very wide 124° diagonal FOV, the supplied specifications do not identify it as a fisheye optical design. It is therefore classified as a Wide Angle Lens, not a Fisheye Lens.

Q: What does BPF850 mean in the optical structure?
A: BPF850 indicates an 850nm bandpass filter configuration. Engineers deploy it for systems targeting a specific near‑infrared wavelength band, and should not treat it as an IR‑corrected optical design.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, or 100mm, allowing the lens to capture scenes at relatively short distances.

Q: What applications are suitable for this 2.1mm M12 lens?
A: Suitable applications include ultra-wide embedded vision, AI vision, robotic perception, near-infrared sensing, equipment monitoring, and other compact imaging systems requiring broad scene coverage.

Q: Does this lens have low distortion?
A: No. The specified TV distortion is less than -5%, so this product should not be positioned as a low-distortion lens. Applications requiring strict geometric accuracy should consider a dedicated low-distortion optical design.

Q: Can Towin customize this lens for an OEM camera project?
A: Customers can assess OEM/ODM requirements against sensor format, FOV, wavelength requirements, mechanical dimensions, housing configuration, and other optical specifications. Contact Towin to discuss a customized camera lens project.
