Low Distortion Lens – CCL14036MPF

CCL14036MPF is 3.6mm low distortion lens with Built-In Filter, F2.2 M6.5×0.25 mount wide-angle lens, 1/4″ 5-megapixel high resolution CCTV lens.

3.6mm M6.5 5MP Low Distortion Miniature Lens

This 3.6mm M6.5 miniature lens is a compact 5MP low-distortion imaging solution designed for space-constrained camera systems that require clear imaging and controlled geometric distortion. With a 62° diagonal field of view, less than 1% distortion, F2.2 fixed aperture, and M6.5×0.25 mount, it provides a practical balance between compact mechanical design, wide-area coverage, and image accuracy.

M6.5 Low Distortion Lens Core Highlights

• Less Than 1% Distortion — The low-distortion optical design helps maintain accurate object geometry for imaging and inspection applications.
• 5MP Resolution — Supports detailed image capture for compact industrial and embedded camera systems.
• Compact M6.5×0.25 Mount — The miniature mount is suitable for optical assemblies where installation space is limited.
• 62° Diagonal FOV — Provides useful wide-area coverage without the extreme geometric distortion associated with fisheye lenses.
• Short 1.3mm BFL — The short back focal length supports compact camera module integration.
• 0.1m Minimum Object Distance — Allows imaging of relatively close subjects in compact inspection and embedded applications.

M6.5 Low Distortion Lens Applications

This M6.5 miniature lens is designed for camera systems that require a small optical footprint while maintaining controlled distortion and 5MP image performance. Its 3.6mm focal length and 62° diagonal FOV make it suitable for applications that need wider scene coverage than a standard narrow-angle lens while still preserving image geometry.

Compact Machine Vision

With distortion below 1%, this lens is well suited to machine vision systems where maintaining the relative shape and position of objects is important. It can be considered for compact inspection cameras, component inspection, positioning systems, and automated imaging equipment.

Designed for compact machine vision and inspection applications.

Embedded Industrial Imaging

The M6.5×0.25 mount, 1.3mm BFL, and compact optical configuration make this lens suitable for embedded camera modules where available installation space is restricted.

It can be integrated into compact industrial cameras, inspection modules, smart devices, and other imaging equipment requiring a miniature optical assembly.

Robotics Vision

The combination of 5MP resolution, 62° diagonal FOV, and less than 1% distortion can support robotic imaging systems that require reliable spatial representation without using a large lens assembly.

For system-level application information, see TOWIN’s Robotics Vision solution.

Compact Inspection Cameras

The 0.1m M.O.D. provides flexibility for relatively close-range imaging. This makes the lens suitable for compact inspection systems where the target is positioned near the camera and optical space is limited.

Why Choose a Low Distortion Miniature Lens?

A wide field of view is not always enough for an industrial imaging application. When the camera is used to inspect, locate, measure, or recognize objects, excessive geometric distortion can change the apparent shape and position of features within the image.

With distortion specified at less than 1%, this lens is better suited to applications where image geometry needs to remain controlled while still providing a useful 62° diagonal field of view.

Lens Selection Considerations

When selecting a miniature lens, the optical parameters should be evaluated together with the mechanical requirements of the camera module. The 1/4″ image format, 3.6mm focal length, 62° diagonal FOV, 1.3mm BFL, and M6.5×0.25 mount should all be matched with the target camera and sensor configuration.

The short 1.3mm BFL can be particularly useful in compact camera assemblies, while the 0.1m M.O.D. provides close-range imaging flexibility.
