M7 Low Distortion Lens Applications

Core Application Scenes

This 2.65mm wide angle lens is particularly suitable when the imaging system needs to capture a relatively broad scene while maintaining a compact mechanical footprint. Its 84° diagonal FOV allows the camera to cover more of the target area without requiring a long working distance.

Typical applications include:

• Compact machine vision cameras
• Embedded inspection cameras
• Close-range industrial imaging
• Small-format inspection equipment
• Space-constrained vision modules
• Wide-area object detection
• Compact automation imaging systems
• Embedded monitoring and recognition devices

For applications where geometric accuracy is important, the <1% distortion specification can help reduce optical deformation compared with conventional higher-distortion wide-angle optics. Engineers can also refer to TOWIN’s Distortion Guide when evaluating how lens distortion may affect measurement, inspection, or image processing.

Designed for compact machine vision and embedded imaging applications requiring a wide field of view, controlled distortion, and close-range imaging.

Compatible Devices

The M7X0.35 mount makes this lens suitable for compact camera assemblies where mechanical space is limited. The 1/4″ image format and 5MP resolution should be matched with a compatible image sensor before final optical selection.

Potential device configurations include:

• Compact industrial cameras using 1/4″ sensors
• Embedded vision modules
• Small machine vision camera assemblies
• Compact inspection cameras
• OEM imaging modules
• Space-constrained automation cameras

When selecting a camera and lens combination, sensor size should be checked together with the image circle and field of view. TOWIN’s Sensor Guide can help engineers evaluate sensor compatibility before integrating the lens into a camera system.

Wide-Angle Imaging and Field of View

With a focal length of 2.65mm and an 84° diagonal field of view, this lens is intended for applications where scene coverage is more important than achieving a narrow viewing angle.

The actual horizontal and vertical field of view will depend on the selected sensor and its dimensions. For system-level optical planning, the FOV Calculator can be used to estimate the relationship between sensor size, focal length, working distance, and field of view.

Close-Range Imaging

The specified 0.1m M.O.D. makes the lens suitable for imaging scenarios where the camera needs to operate relatively close to the target. This can be useful in compact inspection equipment where the available installation distance is limited.

The manual focus design allows the optical system to be adjusted during mechanical integration according to the actual working distance.

Compact Mechanical Integration

The M7X0.35 mount and 1.18mm F.B.L. are important when integrating the lens into a compact camera housing. Mechanical clearance, sensor position, mounting tolerance, and optical alignment should all be considered during system design.

For broader optical integration considerations, see TOWIN’s Optical Design resources.

Lens Selection Considerations

When replacing or selecting a compact wide-angle lens, engineers should evaluate several parameters together rather than choosing a lens only by focal length.

The most important factors for this lens include:

1. Sensor Format: The lens is specified for a 1/4″ image format.
2. Resolution: The 5MP specification should be considered together with the camera sensor and image-processing requirements.
3. Field of View: The 84° diagonal FOV provides wide scene coverage.
4. Distortion: <1% distortion makes it suitable for applications where image geometry needs to remain relatively controlled.
5. Working Distance: The 0.1m M.O.D. should be considered when determining the installation position.
6. Mechanical Mount: The M7X0.35 mount must match the camera or optical housing.
7. Aperture: The fixed F2.0 aperture should be evaluated according to the system’s lighting conditions.

For a broader selection workflow, engineers can refer to the Lens Selection Guide.

Frequently Asked Questions

Q1: What is the field of view of this 2.65mm M7 lens?

A: The lens provides an 84° diagonal field of view based on the specified optical configuration. Actual horizontal and vertical FOV depend on the sensor dimensions used with the lens.

Q2: Is this a low distortion lens?

A: Yes. The specified distortion is less than 1%, making it suitable for wide-angle imaging applications where geometric deformation needs to be controlled.

Q3: What sensor size is this lens designed for?

A: The specified image format is 1/4″. The camera sensor should therefore be checked for compatibility before integration.

Q4: Is the 2.65mm M7 lens suitable for machine vision?

A: Yes. Its 5MP resolution, 84° diagonal FOV, <1% distortion, F2.0 aperture, and compact M7 mount make it suitable for compact machine vision and embedded imaging systems.

Q5: What is the minimum object distance of this lens?

A: The specified M.O.D. is 0.1m, or 100mm. This allows the lens to be considered for relatively close-range imaging applications.

Q6: Does this lens have adjustable focus?

A: Yes. The focus type is manual. You can adjust this lens during system integration to reach the required focus position.

Q7: What type of mount does this lens use?

A: The lens uses an M7X0.35 mount. Confirm the mechanical interface before you integrate this lens with a camera or custom housing.

Q8: Is this lens a fisheye lens?

A: No. Although the 2.65mm focal length provides a wide 84° diagonal field of view, the specified <1% distortion indicates a controlled-distortion wide-angle design rather than a fisheye lens.
