3.3mm M12 Wide Angle Lens Applications

Core Application Scenes

This 3.3mm M12 wide angle lens is designed for compact imaging systems that need to capture a broad area from a relatively short camera installation distance. Its 121° diagonal field of view provides substantially wider coverage than conventional narrow-angle lenses, making it useful when the camera needs to observe both nearby objects and a wider surrounding scene.

The 0.1m minimum object distance makes the lens particularly suitable for close-range embedded imaging, where the subject may be positioned near the camera. Combined with the F2.0 aperture and fixed focal design, it provides a straightforward optical configuration for dedicated camera modules that do not require variable focal length adjustment.

This lens suits compact surveillance cameras, embedded vision devices, access‑control equipment, smart devices and other space‑constrained imaging platforms. Its M12×0.5 interface lets users integrate it into camera assemblies that demand a small mechanical footprint.

For applications involving compact embedded camera architectures, the M12 Lenses product range provides additional focal length and FOV options. Engineers can also explore M12 Lens solutions for applications requiring compact optical integration.

Designed for compact wide-angle surveillance, embedded vision, access-control, and close-range imaging applications.

Wide-Angle Optical Design

The combination of a 3.3mm focal length and 121° diagonal FOV allows this lens to capture a broad scene while maintaining a compact M12 form factor. This suits camera systems with limited installation space yet needing a relatively large viewing area.

The lens uses a 1/3″ image format and the FOV specification is based on the AR0330 sensor. When integrating the lens with another image sensor, engineers should verify sensor dimensions, image circle compatibility, and the resulting field of view.

For guidance on sensor and lens matching, the Sensor Guide provides useful background information. Engineers can also use the Lens Selection Guide when comparing focal length, sensor format, FOV, and application requirements.

If the required camera geometry is not yet determined, the FOV Calculator can be used to estimate the relationship between sensor size, focal length, and field of view.

The lens also features an IRCF configuration. Engineers working with different spectral or imaging requirements should distinguish between an IR Cut Filter configuration and a dedicated IR-corrected optical design when selecting a lens.

Frequently Asked Questions

Q: What type of lens is this 3.3mm M12 model?
A: It is a fixed focal length M12 wide angle lens designed for compact camera modules. It provides a 121° diagonal field of view with a 3MP resolution specification.

Q: What is the field of view of this M12 wide angle lens?
A: With the AR0330 sensor, the lens provides approximately 121° diagonal, 96° horizontal, and 61° vertical field of view.

Q: Is this lens a fisheye lens?
A: No. Although it provides a wide 121° diagonal field of view, this model is positioned as a wide angle lens rather than a fisheye lens.

Q: What sensor format is this lens designed for?
A: The lens is specified for a 1/3″ image format, with the listed FOV data measured using the AR0330 sensor.

Q: Is the aperture adjustable?
A: No. This model uses a fixed F2.0 aperture and fixed iris, providing stable optical performance for dedicated camera modules.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.1m, making the lens suitable for applications where objects or subjects may be positioned relatively close to the camera.

Q: What does the IRCF configuration mean?
A: IRCF refers to an IR Cut Filter configuration. It should not automatically be interpreted as an IR-corrected optical lens. The actual spectral requirements should be evaluated together with the camera sensor and intended application.

Q: Can this 3.3mm M12 lens be customized for an OEM camera project?
A: Towin can evaluate optical and mechanical requirements for OEM projects, including sensor matching, FOV, housing integration, and other application-specific requirements. Customers can contact Towin to discuss their project.
