This 6mm 4MP M12 low distortion lens is designed for compact imaging systems that require a controlled field of view and accurate image reproduction. With a 60° diagonal FOV, 53° horizontal FOV, and TV distortion below -4.9%, it provides a more balanced optical profile than ultra-wide M12 lenses.
Designed for a maximum image circle of Φ6.8mm and compatible with the OV4689 1/3″ sensor, this fixed focal lens combines 4MP resolution, F1.8 aperture, and M12×0.5 mounting in a compact optical assembly. Its controlled distortion makes it particularly suitable for industrial inspection, embedded machine vision, intelligent monitoring, and applications where excessive image deformation can affect visual analysis.
For compact optical systems requiring improved geometric control, this lens can be evaluated within TOWIN’s M12 Lenses portfolio.
This 6mm M12 low distortion lens is designed for imaging tasks where the camera needs a more controlled perspective than an ultra-wide lens can provide. Its 53° horizontal FOV gives the camera sufficient scene coverage while the <-4.9% TV distortion helps reduce visible geometric deformation.
For industrial inspection and embedded machine vision, controlled distortion can be particularly useful when cameras need to observe components, labels, product surfaces, or equipment features without excessive bending of straight edges. The 4MP resolution provides sufficient detail for many detection and measurement-oriented imaging tasks.
In smart security, the lens can be used where a moderate viewing angle is preferred over an ultra-wide surveillance perspective. The 6mm focal length allows the camera to concentrate more strongly on a defined monitoring area while maintaining useful image detail.
For robotics vision, this lens can serve as a compact vision module for targeted object observation, robotic work areas, and equipment interaction. Its moderate FOV can help avoid the excessive perspective distortion associated with very wide-angle lenses when the robot needs to visually analyze a defined workspace.
The lens is also suitable for embedded industrial cameras and inspection modules where the optical assembly must remain compact while providing controlled image geometry.
Designed for low-distortion industrial inspection, embedded machine vision, and targeted monitoring applications.
For engineers evaluating sensor and lens compatibility, TOWIN’s Sensor Guide can help with the relationship between sensor format and optical image coverage.
In machine vision applications, excessive optical distortion can change the apparent shape and position of objects near the edges of an image. This can complicate visual measurement, alignment, dimensional inspection, and image-based positioning.
With a specified TV distortion below -4.9%, this lens provides a more controlled optical geometry than many extreme wide-angle M12 designs. This makes it a better fit for applications where image geometry is relevant but a large telephoto lens or larger C-mount optical assembly is impractical.
The lens should not, however, be considered a metrology-grade zero-distortion lens without application-specific testing. Actual measurement accuracy depends on the complete camera system, calibration, sensor characteristics, working distance, and image-processing method.
For further information about optical distortion and lens selection, see TOWIN’s Distortion Guide.
The 6mm fixed focal length provides a more targeted viewing area than the 3mm-class wide-angle M12 lenses commonly used for broad scene coverage. This makes it suitable when the camera should concentrate on a particular object, work area, or monitoring zone.
The F1.8 aperture provides useful light-gathering capability while keeping the optical configuration compact. This can benefit indoor industrial environments, equipment monitoring areas, and embedded vision systems with controlled or moderate illumination.
The lens has a 20.98mm T.T.L. and M12×0.5 mounting interface. Mechanical clearance, sensor position, and the required back focal configuration should be verified during camera integration.
For optical system planning, the Optical Design section provides additional information for engineers evaluating lens construction and imaging performance.
Q: What type of lens is the 6mm 4MP M12 lens?
