S03213009322F

S03213009322F is a 3.2mm M12 wide-angle lens. It is for 1/3″ 1/2.9″ sensors like AR0330, AR0130, OG02B10, PS1210K. It is a 3 Megapixel HD lens with short T.T.L. for Car driving recorder.

Product Overview

This 3.2mm M12 wide-angle lens is developed for compact camera modules that need broad environmental coverage without relying on an extreme fisheye perspective. Designed around the 1/3″ AR0130 sensor, it delivers 3MP imaging with a 126° diagonal field of view, 93° horizontal field of view, and 67° vertical field of view. The F2.2 fixed aperture provides a balanced optical configuration for embedded cameras, while the M12x0.5 mount allows straightforward integration into small board-camera assemblies. With optical distortion below 29%, the lens provides a wide-angle perspective suitable for scene monitoring, object detection, and environmental awareness. Its 16.81mm total track length and 5G+IRF construction are designed for compact camera integration. Designed for wide-area embedded imaging applications, this lens is well suited to smart security, robotics, compact monitoring equipment, and intelligent camera systems.

Product Advantages

Broad Coverage for Embedded Cameras
The 126° diagonal FOV provides extensive scene coverage, allowing compact cameras to monitor a relatively large area without requiring an extremely short focal length.

AR0130 Sensor Compatibility
The lens is specifically configured around the 1/3″ AR0130 sensor, providing a practical optical solution for camera modules built around this sensor platform.

Balanced Wide-Angle Perspective
Compared with extreme fisheye optics, the 3.2mm configuration offers a more moderate wide-angle perspective, making it suitable for applications where both coverage and recognizable image geometry are important.

3MP Imaging Performance
The 3MP optical configuration provides sufficient detail for monitoring, detection, and embedded vision applications where compact camera size and broad coverage are key priorities.

Compact M12x0.5 Interface
The M12x0.5 mount supports integration into small camera modules, embedded vision devices, and space-constrained optical assemblies.

Fixed F2.2 Aperture
The F2.2 aperture provides a balanced combination of optical brightness, compact design, and practical imaging performance for general-purpose embedded camera systems.

5G+IRF Optical Construction
The 5G+IRF construction provides a compact multi-element optical configuration with an integrated infrared filter component for visible-light imaging applications.

Applications

Smart Security Cameras
The 126° diagonal field of view is well suited to compact security cameras that need to monitor rooms, entrances, corridors, or other relatively broad areas.

Robotics & Mobile Platforms
A broad horizontal FOV of 93° allows the camera to capture substantial environmental information, which can be useful for robotic navigation, obstacle awareness, and surrounding-scene detection.

See Robotics Vision for additional optics designed for robotic imaging systems.

Embedded Vision Devices
The combination of a compact M12 mount, 1/3″ sensor format, and broad FOV makes this lens suitable for embedded cameras where optical size and environmental coverage must be balanced.

Intelligent Monitoring Systems
The lens can support compact monitoring devices that need to detect people, objects, or environmental changes across a relatively large viewing area.

Indoor Surveillance
The 93° horizontal and 67° vertical FOV provide useful coverage for indoor environments where a wide viewing angle is required without the highly curved perspective of extreme fisheye lenses.

Compact AI Camera Modules
The lens can be integrated into embedded AI cameras where the camera system needs broad visual input for detection and scene understanding.

Optical Performance & Selection Considerations

Wide-Angle Coverage
The 3.2mm focal length provides 126° diagonal, 93° horizontal, and 67° vertical FOV with the specified AR0130 sensor. This makes the lens particularly useful when horizontal scene coverage is a major system requirement.

For calculating coverage according to camera geometry, use TOWIN’s FOV Calculator.

Distortion Characteristics
The specified distortion is below 29%. This is considerably more controlled than the extreme distortion found in dedicated fisheye designs, while still providing a wide viewing angle. The lens is therefore better suited to general monitoring and object detection than precision dimensional measurement.

For more information about distortion and its effect on imaging, see the Distortion Guide.

Sensor Matching
This lens is designed for a 1/3″ image format and is specified for the AR0130 sensor. Matching the sensor dimensions and optical image format is essential for obtaining the intended FOV and avoiding image-circle limitations.

More information is available in TOWIN’s Sensor Guide.

Aperture and Illumination
The F2.2 fixed aperture offers a balanced configuration for general embedded imaging. Actual exposure performance depends on sensor sensitivity, illumination, exposure settings, and image-processing characteristics.

Optical Construction
The 5G+IRF construction combines multiple optical elements with an infrared filtering component. This configuration is intended for visible-light camera systems where unwanted infrared transmission needs to be controlled.

Mechanical Integration
The M12x0.5 mount and 16.81mm TTL make this lens suitable for compact camera assemblies. Mechanical clearance, sensor position, and required focus distance should be verified during camera integration.

Frequently Asked Questions

Q: What is the main advantage of this 3.2mm M12 wide-angle lens?
A: Its main advantage is the combination of broad 126° diagonal coverage, 3MP imaging, and a more moderate distortion profile than extreme fisheye lenses, making it suitable for compact monitoring and embedded vision systems.

Q: Which image sensor is this lens designed for?
A: The lens is designed for a 1/3″ image format and is specified for the AR0130 sensor. The optical and sensor combination should be verified during camera development to achieve the specified field of view.

Q: Is this lens considered a fisheye lens?
A: It is an ultra-wide-angle configuration, but its distortion specification of below 29% is more moderate than many dedicated fisheye lenses. It is better suited to applications requiring broad coverage with a less extreme perspective.

Q: What applications are suitable for this lens?
A: Typical applications include smart security cameras, indoor monitoring, robotics vision, embedded AI cameras, intelligent monitoring devices, and other compact systems requiring broad environmental coverage.

Q: Does the M12 wide-angle lens have an adjustable iris?
A: No. The lens uses a fixed F2.2 aperture. This provides a consistent optical configuration and simplifies integration into compact camera modules.
