4.0mm M12 Wide Angle Lens Applications

Core Application Scenes

The combination of 4.0mm focal length, 140° diagonal FOV, 8MP resolution, and F1.6 aperture makes this lens suitable for applications requiring broad scene coverage together with high image detail.

Typical applications include:

• Automotive surround vision: The 140° diagonal FOV provides extensive coverage around vehicles and equipment.
• Vehicle-mounted monitoring: The 121° horizontal FOV is suitable for capturing broad lateral scenes.
• Smart traffic imaging: The combination of 8MP resolution and wide-angle coverage supports detailed road-scene monitoring.
• Outdoor intelligent cameras: IP67/IP69K protection supports demanding outdoor installations.
• Embedded AI vision: High-resolution wide-area imaging provides extensive visual information for object detection and scene analysis.
• Robotics vision: The broad FOV can support environmental perception and obstacle awareness.
• Wide-area industrial monitoring: The optical configuration can cover large areas from a relatively compact camera position.

Designed for automotive surround vision, smart traffic, outdoor monitoring, robotics vision, and high-resolution wide-area imaging applications.

Ultra-Wide Optical Performance

The lens provides an impressive 140° diagonal field of view with the 1/1.73-inch OX08B40 sensor. The corresponding horizontal and vertical FOVs are approximately 121° and 67°.

The specified < -57% distortion is characteristic of the lens’s extreme wide-angle optical behavior. This is not a low-distortion design; instead, the optical configuration prioritizes capturing a very large scene within a compact camera system.

This makes the lens suitable for applications where wide-area coverage and situational awareness are more important than maintaining rectilinear image geometry.

For applications requiring accurate geometric imaging, TOWIN’s Low Distortion Lens category provides alternative optical solutions.

8MP OX08B40 Compatibility

The lens is specifically designed for the 1/1.73-inch OX08B40 8MP sensor, allowing the optical system to combine high image resolution with a very broad field of view.

The resulting configuration provides:

• 8MP resolution
• 140° diagonal FOV
• 121° horizontal FOV
• 67° vertical FOV
• 4.0mm focal length
• F1.6 aperture

This combination is particularly useful for vision systems that need to observe a broad scene while retaining sufficient image detail for intelligent analysis.

F1.6 Large Aperture

The F1.6 aperture provides a relatively high level of light-gathering capability, which can be beneficial in automotive, outdoor, and other variable-light environments.

The combination of F1.6 aperture and an 8MP sensor can support applications where maintaining usable image brightness and image detail is important.

Actual low-light performance will also depend on sensor sensitivity, exposure settings, illumination, and the complete camera system.
