2.7mm M7 Low Distortion Lens Applications

Core Application Scenes

This 2.7mm M7 5MP wide angle lens is designed for compact imaging systems that need to capture a relatively broad scene from a limited installation space. Its 84° diagonal field of view provides wider coverage than conventional longer-focal-length miniature lenses, while the <1% distortion specification helps maintain a more controlled image geometry.

The combination of a 2.7mm focal length, 69° horizontal FOV, and 58° vertical FOV makes the lens suitable for close-range monitoring and inspection where the camera cannot be positioned far from the target. The 0.1m minimum object distance further supports compact equipment in which the imaging target is located close to the camera.

Featuring 5MP resolution and an F2.0 aperture, this lens targets embedded industrial cameras, compact inspection modules, robotic vision devices, and other small‑form‑factor imaging equipment. Its M7 × 0.35 mount is particularly useful when the optical assembly must fit into a restricted mechanical envelope.

For engineers selecting a lens according to sensor size, focal length, working distance, and required coverage, the Lens Selection Guide provides a useful starting point for optical configuration.

Compatible Device List

• Compact Machine Vision Cameras: Suitable for 1/4″ camera modules requiring 5MP imaging and broad scene coverage.
• Embedded Inspection Cameras: The compact M7 × 0.35 mount helps integrate the lens into space-limited inspection equipment.
• Robotic Vision Modules: The wide FOV can help capture nearby objects within a constrained robot-mounted camera position.
• Compact Industrial Monitoring Devices: Suitable for equipment monitoring where the camera needs to observe a relatively broad area from a short distance.
• OEM Camera Modules: The fixed focal length, manual focus, and fixed iris provide a straightforward configuration for dedicated imaging products.
• Close-Range Vision Systems: The 0.1m M.O.D. supports applications where the target is positioned close to the camera.

Designed for compact wide-angle machine vision and close-range industrial imaging applications.

Optical Selection Considerations

The key characteristic of this lens is its combination of short 2.7mm focal length and 84° diagonal FOV. This configuration provides broad image coverage while remaining different from an extreme fisheye design. The lens therefore offers an option for applications that require wider coverage but still need controlled geometric distortion.

The <1% distortion specification is particularly relevant when the captured image will be used for object positioning, visual inspection, alignment, or other image-processing tasks where excessive geometric deformation can affect image interpretation.

The lens uses a manual focus and fixed iris, making it suitable for camera systems where the installation distance and lighting conditions can be established during equipment setup. Its 1.17mm F.B.L. should also be considered when designing the camera housing and sensor-to-lens mechanical interface.

For applications requiring a broader viewing area, the Wide Angle Lens range provides additional wide-angle optical configurations.

Engineers evaluating distortion requirements can refer to the Distortion Guide to understand how optical distortion can affect image geometry in machine vision systems.

Frequently Asked Questions

Q: What sensor size is this 2.7mm M7 lens designed for?
A: This lens is designed for a 1/4″ image format and supports 5MP resolution.

Q: What is the field of view of the 2.7mm lens?
A: The specified field of view is 84° diagonal, 69° horizontal, and 58° vertical.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a wide 84° diagonal field of view, its specification does not indicate a fisheye optical design. It is classified as a wide angle lens rather than a fisheye lens.

Q: Is the 2.7mm M7 lens suitable for machine vision?
A: Yes. Its 5MP resolution, <1% distortion, 0.1m M.O.D., and compact M7 mount make it suitable for compact machine vision and industrial imaging systems.

Q: What mount does this lens use?
A: The lens uses an M7 × 0.35 mount, making it suitable for miniature camera modules and space-constrained embedded vision equipment.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, or 100mm, allowing the lens to be used for relatively close-range imaging.

Q: Does this lens have an adjustable focus?
A: The specification identifies the focus as Manual, allowing the optical focus to be adjusted during system setup.

Q: Does this lens include an IRCF?
A: No. The specification states Without IRCF. If an IR-cut filter is required, the filter configuration should be considered separately within the camera system.
