Wide Angle Lens Applications

Core Application Scenes

This 8MP M12 fisheye lens is designed for vision applications where extremely wide scene coverage is a primary requirement. Its 176° diagonal FOV enables a single camera to observe a very large area, reducing blind spots in applications such as panoramic surveillance, compact embedded vision, and near-field environmental monitoring.

For panoramic CCTV, the lens can be integrated into compact security cameras positioned in rooms, retail environments, entrances, lobbies, and other locations where broad coverage from a single camera is preferred. Its 153° horizontal FOV is particularly useful when the camera needs to monitor a wide horizontal area without relying on multiple imaging modules.

In industrial environments, the lens can be used for wide-area machine and equipment observation, especially where the camera is mounted close to the monitored zone. The 0.2m M.O.D. provides practical flexibility for short-range imaging, while the 8MP resolution helps preserve useful image detail across the captured scene.

The ultra-wide optical configuration can also support selected automotive surround-view and near-field vision systems, provided the lens distortion characteristics are properly compensated by the camera’s image-processing system. Unlike a low-distortion industrial lens, this product is intentionally optimized for maximum coverage rather than geometric accuracy.

Designed for panoramic surveillance, ultra-wide embedded vision, and short-range industrial monitoring applications.

For projects where extremely wide coverage is required, the M12 Lenses product range provides additional compact lens options. Engineers can also use the FOV Calculator to evaluate the relationship between sensor size, focal length, and required viewing coverage.

Because this lens has intentionally high fisheye distortion, designers should also review the Distortion Guide when determining whether the optical characteristics match their image-processing requirements.

Related Optical Selection Resources

Selecting an ultra-wide lens requires more than comparing focal length alone. Sensor format, image circle, field of view, distortion, working distance, and mechanical dimensions should all be considered during optical selection.

For engineers developing an embedded or compact camera, the Lens Selection Guide provides additional guidance on matching lens characteristics with system requirements. The Sensor Guide can also help evaluate sensor and lens compatibility.

For applications involving robotics and industrial automation, this lens can be considered alongside TOWIN’s Robotics Vision and Machine Vision optical solutions. For project-specific requirements or OEM/ODM development, customers can Contact TOWIN.
