Wide Angle Lens – S03212810616F1

S03212810616F1 is 1/2.8″ 3.2mm High-Quality wide-angle lens, Low F-number M12/S-Mount Lens (F1.6 aperture), 128° 2-Megapixel resolution CCTV lens.

3.2mm M12 Wide Angle Lens

This 3.2mm M12 wide angle lens is designed for compact camera modules and embedded vision systems that require a broad field of view within a limited installation space. With a 128° diagonal FOV, F1.6 aperture, and 1/2.8″ image format, the lens provides wide-area image coverage while maintaining a compact M12 form factor.

The fixed focal length design and M12×0.5 mount make this lens suitable for space-constrained imaging devices, smart security cameras, robotics, industrial monitoring equipment, and embedded machine vision applications. Its 0.3m minimum object distance also allows the lens to capture relatively close subjects without requiring an extended working distance.

For projects requiring a compact wide-angle optical solution, this lens can be considered alongside other options in our M12 Lenses range.

M12 Wide Angle Lens Core Highlights

• 128° Ultra-Wide Field of View — Covers a broad scene with a 3.2mm focal length, making it suitable where camera coverage is more important than telephoto reach.
• F1.6 Large Aperture — Helps provide stronger light-gathering capability for indoor and relatively low-light imaging environments.
• Compact M12×0.5 Mount — Designed for small camera modules, embedded devices, and space-constrained optical assemblies.
• 2MP Imaging Performance — A practical resolution level for monitoring, detection, presence sensing, and general-purpose embedded vision.
• 0.3m Minimum Object Distance — Supports close-range imaging applications where the camera needs to observe subjects at relatively short distances.

M12 Wide Angle Lens Applications

Core Application Scenes

The combination of a 3.2mm focal length, 128° diagonal FOV, F1.6 aperture, and compact M12 mount makes this lens particularly suitable for applications requiring broad scene coverage from a relatively small camera module.

Typical applications include:

• Smart security and indoor monitoring cameras
• Embedded vision systems
• Robotics and mobile robot cameras
• Industrial equipment monitoring
• Machine status and presence detection
• Smart home and IoT imaging devices

• Space-constrained vision equipment

Designed for compact wide-angle vision applications, this lens is a practical option when installation space is limited but a large viewing area is required.

For broader application development, it can also be evaluated with TOWIN’s Machine Vision and Robotics Vision optical solutions.

Compatible Device Types

This M12 wide angle lens can be integrated into:

• 1/2.8″ CMOS camera modules
• Embedded vision cameras
• Compact IP camera modules
• Robotics cameras
• Industrial monitoring cameras
• Smart security devices
• IoT vision devices
• Edge AI camera systems
• Small-format machine vision cameras

The M12×0.5 interface is widely used in compact camera designs, making the lens convenient for integration into customized camera housings and embedded optical systems.

Optical Design Considerations

A 3.2mm focal length provides a significantly wider viewing angle than conventional longer-focal-length lenses on the same sensor format. This makes the lens useful when the camera must capture more of the surrounding environment without increasing the physical distance between the camera and the subject.

The <-50% distortion specification reflects the lens’s wide-angle optical design. Therefore, this product should be selected when broad scene coverage is a priority rather than when highly geometrically accurate imaging is required.

For projects where distortion characteristics are a critical selection factor, engineers can also refer to TOWIN’s Distortion Guide when comparing different lens designs.

The F1.6 fixed aperture provides a relatively large optical opening, helping the camera collect sufficient light in indoor or moderately dim environments. Combined with the 1/2.8″ image format, this configuration is well suited to compact vision systems where both optical size and scene coverage need to be considered.

Related Optical Resources

When selecting an M12 lens, the relationship between sensor size, focal length, field of view, and distortion should be evaluated together. TOWIN provides additional resources through the Lens Basics, Sensor Guide, and Lens Selection Guide.

For projects where the required focal length needs to be calculated from the target field of view and sensor dimensions, the Focal Length Calculator can also be used as a preliminary lens-selection tool.
