Low Distortion Lens – S07011009228

S07011009228-102° 20MP Low Distortion Wide angle manual focus fixed-iris fixed-zoom M16X0.5 mount lens

7mm 20MP M16 Low Distortion Wide Angle Machine Vision Lens

This 7mm 20MP M16 wide angle lens is designed for high-resolution industrial imaging systems that require a broad field of view with exceptionally low geometric distortion. Supporting a 1″ image format, 102° diagonal FOV, 20MP resolution, and less than 2.9% distortion, it provides a strong combination of image detail, scene coverage, and optical precision for machine vision and industrial inspection applications.

With an M16×0.5 mount, F2.8 fixed aperture, manual focus, and a 3.97mm back focal length, this fixed focal lens is well suited to demanding compact vision systems where high-resolution imaging and controlled distortion are essential.

Low Distortion Lens Applications

This 7mm M16 lens is designed for industrial vision systems where high resolution and low distortion must be achieved together with a wide field of view. The combination of 20MP resolution and <2.9% distortion makes it particularly suitable for applications that need to inspect or measure multiple features across a relatively large working area while preserving accurate image geometry.

Designed for high-resolution machine vision inspection, this lens can be integrated into industrial cameras used for large-area surface inspection, electronic component inspection, dimensional checking, printed circuit board inspection, packaging inspection, and automated quality control. Its 1″ image format and 20MP resolution allow the camera system to capture fine details while covering a wider portion of the inspection area.

The low distortion performance is especially valuable when the image is used for geometric analysis, object positioning, edge detection, pattern recognition, or measurement-related vision tasks. Compared with conventional wide angle optics, the <2.9% distortion specification helps reduce image deformation toward the edges of the frame.

The 0.2m minimum object distance also supports relatively close-range inspection setups, making the lens practical for compact production-line vision stations where the camera has limited working distance.

For high-resolution industrial imaging projects, this lens can be evaluated alongside TOWIN’s Industrial Lens solutions and Machine Vision applications. Engineers looking specifically for controlled geometric performance can also explore TOWIN’s Low Distortion Lenses range.
