Wide Angle Lens – S02113012322F

S02113012322F is 2.1mm Compact Wide angle 1/3″ M12-mount lens with Built-In Filter, 3-Megapixel resolution, 160° F2.2 security surveillance lens.

3MP 2.1mm M12 Wide Angle Lens

This 3MP M12 ultra wide angle lens is designed for compact camera modules that require an exceptionally broad field of view in a 1/3″ image format. With a 2.1mm fixed focal length, the lens provides a 160° diagonal FOV, 123° horizontal FOV, and 90° vertical FOV, allowing a single camera to capture a large surrounding area.

Featuring an F2.2 aperture, M12×0.5 mount, 0.2m minimum object distance, and 6G optical construction with an IR cut filter, this lens is suitable for wide-area monitoring, embedded vision, smart security, and other compact imaging systems where maximizing scene coverage is a priority.

M12 Wide Angle Lens Core Highlights

• 160° ultra-wide field of view: The 2.1mm focal length provides an extremely broad diagonal FOV for applications requiring maximum scene coverage.
• 1/3″ sensor compatibility: Designed around a common compact sensor format for embedded cameras and wide-angle imaging modules.
• 3MP resolution: Provides a practical balance between image detail and ultra-wide scene coverage for monitoring and embedded vision applications.
• 0.2m minimum object distance: Supports relatively close-range wide-area imaging where the camera needs to observe nearby objects across a broad scene.
• M12×0.5 compact mount: Enables integration into space-constrained camera modules and embedded imaging equipment.

M12 Wide Angle Lens Applications

Core Application Scenes

This 2.1mm M12 Wide Angle lens is designed for imaging systems where maximum scene coverage is more important than maintaining a rectilinear image. Its 160° diagonal FOV allows a compact camera to capture a very large portion of the surrounding environment from a single installation point.

Designed for ultra-wide monitoring applications. The lens is particularly suitable for indoor surveillance, compact security cameras, embedded monitoring systems, and other devices that need to minimize blind spots while maintaining a compact optical structure.

Recommended applications include:

• Wide-area indoor surveillance
• Smart security cameras
• Panoramic monitoring
• Compact embedded cameras
• Smart home vision devices
• IoT imaging systems
• Robotics environment perception
• Indoor navigation
• Wide-angle scene monitoring
• Compact camera modules

The 123° horizontal FOV is especially useful when the camera’s primary requirement is broad horizontal coverage. For security-oriented applications, it can help a single camera observe a wider area from a fixed mounting position. Related applications can be found in TOWIN’s smart security solutions.

The 0.2m MOD also makes this lens suitable for relatively close-range observation, such as monitoring spaces where objects may appear near the camera.

Compatible Devices

This M12 ultra-wide lens can be integrated into:

• 1/3″ camera modules
• M12-mount IP cameras
• Compact surveillance cameras
• Smart security devices
• Embedded vision cameras
• IoT camera modules
• Panoramic imaging devices
• Robotics vision modules
• Indoor monitoring systems

For applications requiring different focal lengths, sensor formats, or fields of view, TOWIN provides a broader M12 lens product range.

Optical Performance Considerations

With a 160° diagonal field of view and specified horizontal distortion below -39%, this lens is intended for ultra-wide image capture rather than precision geometric measurement.

The high field of view is advantageous when the primary objective is to maximize visible area, reduce blind spots, or capture environmental context from a compact camera position. Applications requiring highly accurate dimensions, straight-line preservation, or precision measurement should evaluate the distortion characteristics before selecting this optical design.

For engineers comparing wide-angle optical solutions, TOWIN’s lens distortion guide provides additional information about how distortion affects different imaging applications.

The 0.2m minimum object distance is another useful characteristic for close-range monitoring, especially where the camera needs to observe objects positioned relatively near the lens.

Frequently Asked Questions

Q: What type of lens is this 2.1mm M12 lens?
A: It is a fixed focal length M12 ultra-wide angle lens with a 160° diagonal field of view. Its extremely wide coverage makes it suitable for fisheye-style imaging applications.

Q: What sensor size is this lens designed for?
A: The lens is designed for a 1/3″ image format. The sensor and mechanical camera configuration should be verified during system integration.

Q: What is the field of view of this M12 Wide Angle lens?
A: The lens provides a 160° diagonal FOV, 123° horizontal FOV, and 90° vertical FOV with a 2.1mm focal length.

Q: Is this lens suitable for 3MP cameras?
A: Yes. The lens is specified for 3MP resolution and is suitable for camera modules requiring wide-area image capture with a 1/3″ sensor format.

Q: Is this an IR corrected lens?
A: No. The optical construction includes IRCF, which refers to an IR cut filter. An IR cut filter should not be confused with an IR corrected optical design.

Q: Is this lens suitable for machine vision?
A: It can be used for machine vision or embedded perception applications where extremely wide scene coverage is required. However, the specified distortion makes it less suitable for precision measurement applications where geometric accuracy is critical.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, allowing the lens to capture relatively close objects while maintaining its wide field of view.

Q: Can this M12 lens be customized for a specific camera module?
A: TOWIN can evaluate OEM/ODM requirements for customized optical and mechanical solutions. Sensor format, FOV, working distance, mounting interface, and application requirements can be provided for evaluation through the contact page.
