C-mount is the most common standard for scientific and industrial cameras, based on a 1” / 25.4mm screw thread, with the camera offering the female side. However, for large format CMOS cameras, C-mount can limit the effective area of the sensor, providing up to 22mm diagonal field of view.

For larger formats, F-mount is another common standard in scientific cameras, based on a three-lug bayonet mount with a 44mm maximum diagonal field of view.

Also available on some cameras is the M42 mount, based on a 42mm screw thread, a common standard for photography cameras and lenses.

Some cameras however offer complete customization over the mounting mechanism.
