6.5mm 5MP M12 Ultra Low Distortion Lens

This 6.5mm 5MP M12 ultra low distortion lens is designed for compact imaging systems that require exceptional geometric accuracy in a space-efficient optical package. Featuring optical distortion below 0.1%, the lens helps maintain accurate object shapes and image geometry for inspection, measurement, recognition, and embedded vision applications. Designed for a 1/2.5″ image format, it delivers 5MP resolution with a 56° diagonal field of view, providing a balanced viewing range for compact camera systems. The F4.0 fixed aperture, M12 × 0.5 mount, and 2G2P + IR Cut optical construction support stable integration into embedded camera modules. Its particularly compact Φ14 × 9mm dimensions and 10.61mm T.T.L. make it suitable for applications where installation depth is highly restricted. With a 0.1m M.O.D. and 1.51mm M.B.F.L., this lens provides flexible close-range integration. Designed for precision low-distortion imaging applications, it combines ultra-low distortion, 5MP resolution, and an exceptionally compact form factor.

Compact Inspection Systems

The lens combines 5MP resolution with exceptionally low distortion and a very compact Φ14 × 9mm mechanical design. This makes it suitable for inspection modules where both image accuracy and limited installation space are important considerations.

The 0.1m M.O.D. also allows the lens to be positioned relatively close to inspection targets.

Embedded Vision Devices

The M12 × 0.5 mount and 10.61mm T.T.L. make this lens suitable for embedded camera modules and space-constrained vision devices. Its short optical length can help simplify integration into compact equipment where a conventional lens assembly may occupy excessive internal space.

Measurement & Recognition Cameras

Ultra-low distortion can be particularly valuable when cameras are used for image-based measurement, object recognition, alignment, or positioning. Keeping distortion below 0.1% helps reduce geometric deformation across the captured image and can simplify downstream image-processing requirements.

For more information about distortion and its effect on imaging accuracy, see the Distortion Guide.

Compact Robotics Vision

Robotic vision modules may need to fit within restricted mechanical spaces while maintaining reliable image geometry. The combination of 5MP resolution, 56° diagonal FOV, <0.1% distortion, and Φ14 × 9mm dimensions makes this lens a strong candidate for compact robotic cameras and embedded positioning systems.

Q: What is the field of view of the 6.5mm lens?
A: The specified diagonal field of view is 56°.

Q: Why is <0.1% distortion useful for machine vision?
A: Extremely low distortion helps preserve the actual shape and relative position of objects in the image, which is valuable for inspection, measurement, positioning, and recognition tasks.

Q: Is this lens suitable for space-constrained camera modules?
A: Yes. The Φ14 × 9mm dimensions and 10.61mm T.T.L. provide a highly compact optical configuration for embedded camera designs.

Q: What is the difference between M.B.F.L. and M.O.D.?
A: M.B.F.L. refers to the minimum back focal length specification provided for the optical system, while M.O.D. indicates the minimum object distance at which the lens can focus on a target. For this lens, the specified M.B.F.L. is 1.51mm and M.O.D. is 0.1m.

Q: What is the purpose of the IR Cut component?
A: The 2G2P + IR Cut construction indicates that an IR-cut component is included in the optical configuration to help control infrared wavelengths and support visible-light imaging. It should not be described as an IR Corrected lens unless an IR correction specification is provided.
