Wide Angle Lens Applications

Core Application Scenes

This 4mm M12 wide angle lens is designed for camera systems that need a broad viewing area while maintaining a more moderate wide-angle perspective than an extreme fisheye lens. With up to 107° diagonal FOV on a 1/2.7″ sensor, it can capture a large scene from a relatively compact camera position.

The F1.0 aperture is a key advantage for applications operating under limited illumination. By allowing a high amount of light into the optical system, it can help compact cameras maintain usable image brightness in indoor environments, equipment areas, entrances, and other scenes where available light may vary.

The 5MP optical configuration makes the lens suitable for embedded camera platforms requiring more image detail than basic surveillance modules. The M12X0.5 mount also provides a compact mechanical interface for camera modules with limited installation space.

The integrated filter structure makes this model suitable for camera assemblies where an optical filter needs to be incorporated into the lens configuration. This can simplify integration for customized camera designs and embedded imaging modules.

When selecting a lens according to sensor size, field of view, and focal length, the Sensor Guide and Lens Selection Guide provide useful reference information.

For applications where distortion must be tightly controlled, compare the requirements with the Low Distortion Lens range and review the Distortion Guide.

You can also use the FOV Calculator to estimate the required field of view before selecting the final focal length.

Frequently Asked Questions

Q: What type of lens is this 4mm M12 lens?
A: It is a fixed focal length M12 wide angle lens designed for 1/2.7″ and 1/2.8″ image sensors, with up to 107° diagonal field of view and 5MP resolution.

Q: What is the field of view of this 4mm M12 lens?
A: On a 1/2.7″ sensor, the FOV is 107° diagonal, 90° horizontal, and 48° vertical. On a 1/2.8″ sensor, it is 102° diagonal, 88° horizontal, and 47° vertical.

Q: Is this lens a fisheye lens?
A: This model is classified as a wide angle lens rather than a fisheye lens. Its 107° maximum diagonal FOV provides broad coverage, while its distortion specification is lower than the extreme distortion typically associated with fisheye optics.

Q: What is the advantage of the F1.0 aperture?
A: The F1.0 aperture provides strong light-gathering capability, which can help improve image brightness and maintain usable imaging performance in low-light environments.

Q: What sensors are compatible with this lens?
A: The lens supports 1/2.7″ and 1/2.8″ image formats. The camera designer should also verify the sensor’s active image area, resolution requirements, lens-to-sensor alignment, and mechanical interface.

Q: What does “With Filter” mean in the lens structure specification?
A: Optical configuration includes a filter component. Exact filter specs to be confirmed per target camera design and application requirements.

Q: Is this lens suitable for machine vision?
A: Suitable for machine vision applications needing wide scene observation. Its distortion < -29% requires careful assessment before deployment in precision measurement tasks.

Q: Can Towin customize this 5MP M12 lens?
A: Towin can evaluate customized optical and mechanical requirements based on the target sensor, FOV, filter configuration, housing dimensions, and application. Submit your project requirements through Contact Towin for further evaluation.
