4.0mm 142° Ultra Wide Angle Lens Applications

Core Applications

The combination of a 4.0mm focal length, 142° diagonal FOV, and 8MP resolution makes this lens suitable for imaging systems that need to capture a large scene while maintaining high image resolution.

Designed for ultra-wide-angle imaging applications, this lens can be considered for:

• Industrial vision systems
• Embedded vision cameras
• Wide-area monitoring
• Smart camera systems
• Robotics vision
• Indoor and outdoor monitoring devices
• Panoramic or near-panoramic scene capture
• Intelligent imaging equipment
• Large-area inspection systems
• Compact wide-angle camera modules

For industrial imaging projects, the lens can be evaluated alongside TOWIN’s Machine Vision Lens Solutions, particularly when broad scene coverage is required from a fixed camera position.

Compatible Devices

The lens can be considered for integration with compatible:

• 8MP camera modules
• OX08B40-based imaging systems
• Industrial cameras
• Embedded vision cameras
• Robotics cameras
• Wide-angle monitoring cameras
• Smart camera modules
• Compact machine vision devices

The M16x0.5 mount should be matched with the mechanical interface of the target camera module. Engineers should also verify the available sensor area, lens-to-sensor distance, housing dimensions, and mechanical clearance before integration.

Ultra Wide Angle Optical Design

This lens provides 142° diagonal and 120° horizontal FOV, allowing a large portion of the surrounding scene to be captured from a single camera position. This makes it useful when maximizing scene coverage is more important than maintaining a rectilinear image.

The specified distortion of less than -55% is a significant characteristic of the wide-angle optical design. Users must not treat such distortion as a low‑distortion specification. For applications that demand geometrically corrected images, imaging systems can adopt software‑based dewarping or calibration.

For more information about the relationship between field of view and lens selection, see TOWIN’s Lens Selection Guide.

Engineers can also use the FOV Calculator to evaluate the relationship between sensor size, focal length, and field of view during lens selection.

High-Resolution Wide-Angle Imaging

Supporting 8MP resolution with the OX08B40 sensor makes this lens suitable for applications where both wide scene coverage and image detail are required.

The F1.5 aperture provides a relatively large optical opening, which can be beneficial when the imaging system needs to capture sufficient light. The actual image brightness and low-light performance will also depend on the sensor, exposure settings, illumination conditions, and image-processing system.

When designing an 8MP imaging system, sensor compatibility should be checked carefully. TOWIN’s Sensor Guide provides additional information for matching sensors and lenses.

Frequently Asked Questions

Q: What is the field of view of this 4.0mm lens?
A: With the OX08B40 sensor, the lens provides approximately 142° diagonal, 120° horizontal, and 68° vertical FOV.

Q: Is this lens suitable for wide-angle applications?
A: Yes. Its 142° diagonal FOV and 120° horizontal FOV make it suitable for applications requiring extensive scene coverage.

Q: Is this a fisheye lens?
A: The lens has a very wide field of view and significant optical distortion, but the supplied specifications alone do not confirm a specific fisheye projection. Its classification here is therefore ultra wide angle rather than fisheye.

Q: What sensor is this lens designed for?
A: The listed FOV is measured with the OX08B40 sensor, and the lens supports an image format up to Max. Φ9.3.

Q: Does the -55% distortion mean this is a low distortion lens?
A: No. The -55% specification represents significant wide-angle distortion. It is fundamentally different from a low distortion lens designed to preserve more accurate geometric proportions.

Q: What is the advantage of the F1.5 aperture?
A: The F1.5 aperture provides a relatively large optical opening, helping the imaging system collect light. Actual low-light performance depends on the complete camera system and operating conditions.

Q: Can this lens be used for machine vision?
A: Yes, it can be considered for machine vision applications that require broad scene coverage. The final selection should consider sensor size, working distance, required FOV, resolution, distortion tolerance, and image-processing requirements.

Q: What is the mount type of this lens?
A: The lens uses an M16x0.5 mount. Mechanical compatibility should be verified with the target camera housing and module.
