3mm M5 Low Distortion Lens Applications

Core Application Scenes

This 3mm M5 miniature low distortion lens is designed for compact camera systems that need to inspect objects from a relatively short working distance while maintaining controlled image geometry. Its 0.1m minimum object distance makes it particularly suitable for equipment where the camera is positioned close to the inspection target.

The combination of 2MP resolution and less than 1% TV distortion makes the lens appropriate for visual inspection tasks where image geometry is important. It can be used for detecting component presence, checking object position, monitoring assembly processes, and performing basic visual comparison inside compact automated equipment.

Its 55° diagonal field of view provides a practical balance between coverage and optical control. Unlike an extremely wide-angle or fisheye design, the lens prioritizes a relatively natural image with low distortion, which can reduce the need for aggressive geometric correction during image processing.

The compact 3.65mm T.T.L. and M5 × 0.35 mount make it especially useful for embedded camera modules installed inside machinery, instruments, robotic mechanisms, and other devices where the available optical cavity is limited.

Designed for close-range miniature inspection and compact machine vision applications.

Compatible Device List

• 1/6″ 2MP Camera Modules: Designed for compact imaging systems using 1/6″ CMOS sensors.
• Close-Range Inspection Cameras: The 0.1m M.O.D. supports visual inspection where the camera is installed relatively close to the target.
• Embedded Machine Vision Modules: The short optical length helps integrate the lens into compact automated inspection equipment.
• Miniature Robotics Cameras: Suitable for small robotic vision modules where low distortion and compact dimensions are required.
• OEM Imaging Devices: The M5 × 0.35 mount provides a compact interface for customized camera assemblies.

When determining the required image coverage for a specific installation distance, engineers can use the FOV Calculator to estimate the relationship between sensor dimensions, focal length, and field of view.

For applications requiring careful sensor and lens matching, the Lens Selection Guide provides additional guidance on focal length, sensor format, field of view, and optical requirements.

Close-Range Imaging Performance

The 0.1m M.O.D. is one of the key characteristics of this lens. It allows the camera to be positioned relatively close to the target, making the lens suitable for compact inspection stations and embedded monitoring systems where the available working distance is limited.

The 3mm focal length combined with a 55° diagonal FOV provides useful coverage without the extreme geometric deformation associated with very wide-angle optics. This makes the lens suitable for applications where the imaging system needs to balance target coverage, compact size, and low distortion.

Low Distortion for Visual Inspection

With TV distortion below 1%, the lens maintains controlled image geometry across the field. This is valuable when image-processing algorithms need to determine object position, compare component dimensions, identify edges, or perform basic measurement.

Engineers evaluating the influence of optical distortion on image processing can refer to the Distortion Guide for additional information about distortion characteristics and lens selection.

Compact Optical Configuration

The lens uses a 3P + IRCF optical structure and has a total track length of only 3.65mm. The IRCF specification indicates an IR-cut filter configuration for visible-light imaging; it should not be interpreted as an IR-corrected optical design.

The combination of 2MP resolution, <1% distortion, 0.1m M.O.D., and compact M5 mounting makes this lens a practical choice for miniature cameras integrated into industrial equipment and automated visual inspection systems.
