Wide Angle Lens – S02912811618F

S02912811618F is 2.9mm High-Resolution M12 Wide Angle Lens, 1/2.8″ Low F-number S-Mount Lens (F1.8), high resolution 8 Megapixel CCTV HD lens.

For engineers selecting a lens according to sensor coverage and field of view, the Sensor Guide and FOV Calculator can help evaluate sensor compatibility and viewing-area requirements.

8MP M12 Wide Angle Lens

This 8MP M12 wide angle lens features a 2.9mm focal length, 145° diagonal field of view, and F1.8 aperture for capturing an exceptionally broad scene with compact camera modules. Designed around a 1/2.8″ image format and M12×0.5 mount, it is well suited for embedded vision, panoramic monitoring, automotive surround-view, compact CCTV, and other wide-area imaging applications.

With a fixed focal length, manual focus, fixed iris, and 6G+IRCF optical structure, this lens provides a practical combination of wide scene coverage, high-resolution imaging, and compact integration. It can be integrated into M12 Lenses for applications requiring a small form factor and very wide viewing angle.

M12 Wide Angle Lens Applications

Core Application Scenes

This 8MP M12 wide angle lens is designed for applications where maximizing scene coverage is more important than maintaining low geometric distortion. Its 145° diagonal FOV allows a single compact camera module to monitor a large area, making it particularly useful for panoramic and surround-view imaging.

For automotive surround-view and compact vehicle cameras, the wide viewing angle can help capture areas close to the vehicle that may be difficult to cover with a conventional narrow-angle lens. The compact M12 interface also makes the lens suitable for embedded camera modules where installation space is limited.

In smart security and compact CCTV systems, the 2.9mm focal length allows one camera to cover a broad indoor or semi-enclosed area, reducing blind zones in locations such as entrances, corridors, small retail spaces, elevators, and equipment rooms.

For robotics and embedded machine vision, the lens can provide a wide visual field for navigation, obstacle awareness, and environmental monitoring. It is especially useful where the camera needs to observe a large surrounding area rather than perform precision dimensional inspection.

Designed for ultra-wide-angle embedded vision, panoramic monitoring, automotive surround-view, and compact CCTV applications.

Frequently Asked Questions

Q: What type of lens is this?
A: This is an 8MP M12 wide angle lens with a 2.9mm fixed focal length and 145° diagonal field of view, designed for applications requiring very broad scene coverage.

Q: What sensor size is compatible with this M12 lens?
A: The lens is specified for a 1/2.8″ image format, making it suitable for camera modules using compatible 1/2.8″ sensors.

Q: Is this lens suitable for CCTV applications?
A: Yes. Its 145° diagonal FOV and 2.9mm focal length make it suitable for compact CCTV and security cameras that need broad area coverage from a single camera position.

Q: Is this lens a low distortion lens?
A: No. The specified distortion of less than -69% indicates a strong wide-angle/fisheye optical characteristic. It is designed to maximize field of view rather than minimize geometric distortion.

Q: What is the advantage of the F1.8 aperture?
A: The F1.8 aperture provides relatively strong light-gathering capability, which can benefit wide-angle imaging in indoor environments and other scenes where available illumination is limited.

Q: Can this lens be used for automotive cameras?
A: It can be considered for automotive wide-angle and surround-view camera applications where its 145° field of view is beneficial. Vehicle-specific environmental, optical, and regulatory requirements should be verified for the final application.

Q: What does the M12×0.5 mount mean?
A: M12×0.5 refers to the lens mounting thread, a common interface for compact embedded camera modules and small-form-factor vision systems.

Q: Can TOWIN customize this M12 lens?
A: TOWIN can evaluate optical and mechanical customization requirements for OEM and ODM projects. For project-specific requirements, customers can contact the TOWIN engineering team with sensor, FOV, mechanical, and environmental specifications.
