3.5mm M12 Wide Angle Lens Applications

Core Application Scenes

This 3.5mm M12 Wide Angle lens is designed for imaging systems where maximizing scene coverage is more important than maintaining a conventional rectilinear perspective. Its 150° diagonal field of view allows a single compact camera to capture a very broad area, making it suitable for panoramic observation, surround-view imaging, compact robotic perception, and embedded wide-area vision.

The 108° horizontal and 78° vertical FOV deliver ample lateral and vertical coverage. Its 0.1 m minimum object distance makes the lens especially effective when the camera sits near monitored or inspected zones. This combination can be valuable for compact robotics, indoor panoramic cameras, equipment monitoring, and small-form-factor perception modules.

The F1.2 aperture provides strong light-gathering capability for applications operating under changing illumination. Its fixed‑iris, manual‑focus and fixed‑zoom setup suits systems where technicians mechanically tune the lens during camera assembly, and the unit then runs from a stationary mounting position.

For panoramic and surround-view systems, the significant TV distortion should be considered as part of the optical design. Applications requiring a geometrically corrected output may use software-based image correction or dewarping after image capture. The Distortion Guide provides additional information for engineers evaluating distortion requirements.

The M12 × 0.5 mount makes the lens suitable for compact camera modules and embedded vision assemblies. For engineers matching the lens to a specific sensor, the Sensor Guide can help evaluate sensor format and optical compatibility.
