Select An M12 Lens (S-Mount Lens) For Your Camera

M12 Lenses / S-Mount Lenses

An M12 lens is a miniature lens with 12mm diameter threads. These lenses are also known as S-Mount Lenses or Board Mount Lenses.
M12 lenses are used in robotics,  surveillance cameras, video conferencing, and internet of things cameras.

Types of M12 lenses include fisheye, wide-angle, no-distortion, and telephoto. Our lenses are available with, or without, an IR cut off filter.

Our S-Mount lenses range from 1mm to 50mm focal length and 10° to 230° field of view.

Board mount lenses can be focused following our instructional guide on how to focus a camera.

These miniature lenses can be used with embedded vision systems from Allied VisionBaslere-con SystemsFLIR, iDSThe Imaging Source, Lucid Vision, Vision Components, Ximea, and more.

M12 lenses can also be used with many CS and C Mount cameras.

Our lenses range from 1mm to 50mm EFL and 5° to 230°. The types of M12 lenses include fisheye, wide-angle, no-distortion, and telephoto. Each of our lenses is available with, or without, an IR cut off filter.

These can be used with embedded vision systems and imaging devices from Allied Vision, e-con SystemsFLIR, iDS, Basler, The Imaging Source, Lucid Vision, and more.
