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 Vision, Basler, FLIR, iDS, The 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 30mm EFL and 10° 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, FLIR, iDS, Basler, The Imaging Source, Lucid Vision, and more.

M12 Lens Field of view Calculator

How to Use
Start: Select your sensor, sensor format type, or enter your sensor's output pixel information.
Update: The field of view of each lens is calculated. Image circle coverage (%) is calculated for fisheyes.
Refine: Filter, sort, then open individual product pages for detailed specs and samples.

Our calculator includes advanced distortion models: the web's most accurate wide-angle and fisheye FoV values.
