2.2mm Megapixel M7 Ultra Wide Angle Miniature Lens

This 2.2mm M7 miniature lens is designed for compact imaging systems that require an extremely wide field of view. With a 1/4″ image format, 144° diagonal FOV, F2.4 aperture, M7×0.35 mount, and 0.1m minimum object distance, it is suitable for compact embedded cameras, industrial sensing, robotics, and wide-area imaging applications.

M7 Wide Angle Lens Core Product Highlights

• 144° diagonal FOV: Provides extremely broad scene coverage from a compact 2.2mm focal length.
• 115° horizontal FOV: Captures a wide horizontal scene for applications where camera coverage is more important than geometric accuracy.
• M7 × 0.35 miniature mount: Designed for compact camera modules and space-constrained optical systems.
• 0.1m M.O.D.: Supports very close-range imaging applications.
• F2.4 aperture: Provides a relatively bright optical configuration for compact vision and sensing systems.

M7 Wide Angle Lens Applications

Ultra-Wide-Angle Compact Imaging

The defining characteristic of this lens is its 144° diagonal field of view. With a 2.2mm focal length, it is designed to capture a very broad scene from a small camera package.

The 115° horizontal FOV can be particularly useful when the imaging system needs to monitor a large horizontal area while maintaining a compact optical form factor.

Because the supplied distortion specification is less than -41% horizontally and less than -14% vertically, this lens should be selected for applications where extremely wide coverage is more important than maintaining rectilinear image geometry.

For engineers comparing field-of-view requirements with focal length and sensor dimensions, TOWIN’s FOV Calculator can be used during the initial optical selection process.

Compact Embedded Vision

The M7 × 0.35 mount and 14 mm T.T.L. suit this lens for compact camera architectures with limited optical space.

Potential applications include:

• Embedded vision modules
• Compact industrial cameras
• Smart sensing devices
• Robotic vision modules
• Space-constrained monitoring cameras
• Wide-area sensing systems
• Near-field imaging devices
• Compact inspection equipment

Designed for compact wide-angle imaging applications where maximum scene coverage and small optical dimensions are key requirements.

For additional miniature lens options, the TOWIN M8/M7/M6/M5/M3.5 Small Mount Lenses category provides alternative small-mount optical solutions.

Near-Field Wide-Area Imaging

The 0.1m M.O.D. is an important characteristic for applications that require imaging at relatively short working distances.

Combined with the 144° diagonal FOV, the lens can cover a large scene even when the camera is positioned relatively close to the target. This can be useful in compact robotic systems, embedded sensors, and other installations where the camera cannot be positioned far away from the target.

For machine vision projects requiring a broader optical solution, TOWIN’s Machine Vision Solution provides additional information about industrial imaging applications.

Compatible Devices

This lens is suitable for compact camera modules using a 1/4″ image sensor and an M7 × 0.35 mechanical interface.

The OV9712-based FOV specification is:

• 144° diagonal
• 115° horizontal
• 68° vertical

When integrating the lens, engineers should evaluate the actual sensor dimensions, required scene coverage, working distance, and acceptable distortion together.

For additional information about sensor and optical compatibility, see the TOWIN Sensor Guide.

Distortion and Application Considerations

This lens has a deliberately very wide-angle optical design, and its distortion characteristics are significantly different from a low-distortion machine vision lens.

The specified distortion is less than -41% horizontally and less than -14% vertically. Therefore, this lens should not be selected when accurate geometric representation is the primary requirement.

Instead, its optical design is better suited to applications where maximum scene coverage is the priority.

For example, a compact camera may need to capture a large surrounding area while being installed close to the target. In this situation, the 2.2mm focal length and 144° diagonal FOV can provide substantially broader coverage than a conventional narrow-angle lens.

Engineers requiring controlled geometry should instead review TOWIN’s Distortion Guide and consider a low-distortion lens architecture.

Optical Design and Integration

The lens uses a 5G + IRCF optical construction and has a specified F2.4 aperture.

The fixed iris provides a simple optical configuration for systems with relatively controlled exposure requirements. The 3.5mm B.F.L. and 14mm T.T.L. should also be considered when checking the available mechanical space inside the camera housing.

The M7 × 0.35 mount provides a compact mechanical interface, making the lens suitable for small camera assemblies where standard larger C-mount or CS-mount optics would occupy excessive space.

Frequently Asked Questions

Q: What is the field of view of this 2.2mm M7 lens?
A: With the specified OV9712 sensor, the lens provides 144° diagonal FOV, 115° horizontal FOV, and 68° vertical FOV.

Q: What sensor format is this lens designed for?
A: The specified image format is 1/4″, with the FOV data measured using the OV9712 sensor.

Q: Is this a low-distortion lens?
A: No. This lens is designed for extremely wide-angle coverage, with specified distortion below -41% horizontally and below -14% vertically. It should not be positioned as a low-distortion lens.

Q: Is the 144° FOV equivalent to a fisheye lens?
A: Not necessarily. Although the lens provides a very wide 144° diagonal FOV, the supplied specifications do not identify it as a fisheye lens. Its application should therefore be described as ultra-wide-angle rather than automatically classified as fisheye.

Q: What is the mount of this miniature lens?
A: The lens uses an M7 × 0.35 mount, making it suitable for compact camera modules and miniature imaging systems.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m, allowing the lens to support relatively close-range imaging applications.

Q: What is the aperture of this lens?
A: The lens has a fixed F2.4 aperture.

Q: What applications are suitable for this lens?
A: The lens is suitable for compact embedded vision, wide-area sensing, robotics, industrial imaging, near-field imaging, and other applications where a very wide field of view is more important than low geometric distortion.
