Lensadapters for C-mount lenses

    Lens adapters for industrial cameras

    C-mount to M12 mount adapters, extension rings and focal length extenders for applications where standard lens solution are not providing the optimal field of view at the desired working distance. On the bottom of this page we explain how to use the different type of lens adapters like, C-mount to M12 mount adapter, extension rings and focal length extenders with M12 and C-mount lenses.

    C/CS mount to M12 adapters

    The C or CS mount to M12 lens adapters are used to mount M12 lenses on a C-mount or CS-mount camera. M12 lenses are cheaper, compacter and have less weight. In some applications these parameters are critical. Without this adapter it's not possible to mount a M12 lens on a C or CS-mount industrial camera.

    M12 or C-mount extension rings

    Extensionrings are used to shorten the minimum working distance of a C-mount or M12 lens. Most industrial lenses have a working distance of 100mm or higher. By adding extension rings, this distance can be reduced. When reducing the working distance, the depth of field is also reduced. Adding extension rings willl reduce the optical performance of the lens and the light sensitivity. Therefore M12 or C-mount extension rings are only used in specific industrial applications.

    Focal length extender

    With a focal length extender you can extend the focal length of the lens by a factor 2 or 4. By using this focal length extender in combination with a 35 or 50 or 75mm c-mount lens you can make focal lenghts of 70mm, 100mm, 150mm, 200mm and 300mm.
