Partially coherent image formation with x
... Unlike conventional refractive lenses, the focusing properties of zone plates are based on diffraction. This implies that the focal length of a zone plate lens strongly depends on the wavelength and that multiple diffraction orders exist. In most cases only the first diffraction order is used. The d ...

Partially Coherent Image Formation Theory for X
... Partially coherent image formation theory for a full-field imaging microscope is introduced. Propagation of mutual coherence is presented following Huygens-Fresnel principle. The concept of mutual intensity, together with the quasimonochromatic condition under which it is valid, is also introduced. ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
