M7 Miniature Lens – CCL14032MPR

CCL14032MPR Low Distortion 3.2mm M7 Miniature Lens with 0.1m M.O.D., megapixel resolution and 65° FOV for compact 1/4″ imaging systems.

3.2mm M7 Miniature Low Distortion Lens

This 3.2mm M7 miniature lens is designed for 1/4″ image sensors and delivers megapixel imaging with less than 1% distortion. Its compact M7×0.35 mount, 65° diagonal field of view, fixed F2.5 aperture, and 0.1m minimum object distance make it suitable for compact imaging systems where optical size, geometric accuracy, and close-range coverage are important.

Product Core Highlights

• <1% Low Distortion – Maintains strong geometric accuracy for imaging applications where straight lines and object proportions need to remain well controlled.
• 3.2mm Fixed Focal Length – Provides a 65° diagonal FOV for stable, predictable framing in compact imaging systems.
• Compact M7×0.35 Mount – Suitable for space-constrained camera modules and miniature optical assemblies.
• Megapixel Imaging – Designed to support megapixel-level image capture on 1/4″ sensors.
• 0.1m Minimum Object Distance – Supports close-range imaging where the camera needs to be positioned near the target.

M7 Miniature Lens Applications

Compact Low-Distortion Imaging

The combination of a 3.2mm focal length and less than 1% distortion makes this lens particularly useful when a compact camera needs controlled geometric reproduction. Compared with highly distorted ultra-wide optics, its low-distortion design helps preserve the shape and position of objects across the image.

Designed for compact low-distortion imaging applications where accurate scene geometry is more important than extreme wide-angle coverage.

Embedded Camera Modules

The M7×0.35 mount and 0.7mm back focal length make this lens suitable for compact optical assemblies where installation space is limited. It can be considered for embedded camera modules, miniature inspection devices, compact monitoring equipment, and other systems where a conventional larger C-mount or CS-mount lens would be impractical.

TOWIN provides a broader selection of M8/M7/M6/M5/M3.5 small mount lenses for miniature camera designs requiring different focal lengths and optical configurations.

Close-Range Monitoring

With a specified 0.1m M.O.D., the lens can be positioned relatively close to the subject. This makes it suitable for compact inspection and monitoring systems that need to capture objects at short distances without using a dedicated macro optical configuration.

Potential scenes include:

• Compact equipment monitoring
• Small-object observation
• Embedded inspection cameras
• Close-range product imaging
• Indoor miniature camera modules
• Compact access or monitoring devices

Geometric-Accuracy Applications

The <1% distortion specification is particularly valuable for applications where image geometry matters. It can help reduce the need for aggressive software correction when capturing structured scenes, reference objects, or components that contain straight edges.

For projects where distortion is a key selection criterion, TOWIN’s Distortion Guide provides additional information about distortion characteristics and lens selection.

Compatible Devices

This lens can be considered for:

• M7×0.35 camera modules
• 1/4″ compact cameras
• Miniature embedded cameras
• Compact inspection camera systems
• Small industrial imaging modules
• Close-range monitoring cameras
• Space-constrained optical assemblies
• Compact machine vision subsystems

When selecting the lens for a specific camera, the sensor format, required FOV, mounting interface, working distance, and image quality should be evaluated together. TOWIN’s Lens Selection Guide can help with the optical selection process.

Frequently Asked Questions

Q: What type of camera is this M7 lens designed for?
A: This lens is designed for compact camera modules using 1/4″ image sensors and an M7×0.35 mounting interface. It is suitable for embedded, miniature monitoring, and compact imaging applications.

Q: What makes this a low-distortion lens?
A: The specified distortion is less than 1%, providing controlled geometric reproduction and making the lens suitable for applications where image shape and positional accuracy are important.

Q: What field of view does the 3.2mm lens provide?
A: The specified diagonal field of view is 65°. Actual horizontal and vertical coverage depends on the sensor’s active dimensions.

Q: Is the 3.2mm M7 lens a fixed focal length lens?
A: Yes. The focal length is fixed at 3.2mm and the zoom configuration is fixed, providing consistent framing after installation.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.1m, making it suitable for relatively close-range imaging applications.

Q: What does the M7×0.35 mount mean?
A: M7×0.35 specifies the lens mounting thread, with a 7mm nominal thread diameter and 0.35mm thread pitch. The camera module should use a compatible M7×0.35 interface.

Q: Can this lens be used for machine vision?
A: It may be suitable for compact machine vision or inspection modules where the 1/4″ sensor, megapixel imaging, 3.2mm focal length, and <1% distortion meet the system requirements. Final suitability should be verified against the camera sensor, working distance, MTF, and required image quality.

Q: Why is low distortion important in compact imaging systems?
A: Low distortion helps preserve the geometric relationship between objects in the scene and their image positions. This is useful for inspection, measurement, alignment, and other applications where excessive image deformation could affect analysis.
