There is no theoretical limit to the amount of magnification possible in an optical system, but practical magnification is limited by the system’s resolving power—i.e., its ability to form distinguishable images of objects separated by small angular distances. A unit of magnification commonly used in microscopes and telescopes is the diameter, the magnification in diameters being equal to the number of times the linear dimensions of the object are increased.

Another widely used camera mount is CS-mount. CS-mount lenses are often used in surveillance cameras, and sometimes in low-cost imaging applications. CS-mount lenses have the same thread pitch as C-mount lenses, but the flange focal distance is 12.5 mm.

Magnificationdefinition biology

magnification, in optics, the size of an image relative to the size of the object creating it. Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image. Longitudinal magnification denotes the factor by which an image increases in size, as measured along the optical axis. Angular magnification is equal to the ratio of the tangents of the angles subtended by an object and its image when measured from a given point in the instrument, as with magnifiers and binoculars.

Using a C-CS mount adapter, C-mount lenses can be used on CS camera mounts. Conversely, this does not work, so using CS-mount lenses on C-mount cameras is not possible.

The standard mount for imaging cameras is C-mount with a back focus of 17.526mm. The flange focal distance is the distance between the last surface of the lens and the sensor of the camera. C-Mount also has the thread pitch of 1⁄32 inch and the diameter of 1 inch.
