A rule for how finely a set of optics may be able to distinguish the location of objects that are near each other, proposed by the English physicist Lord Rayleigh. The criterion for resolution is that the central ring in the diffraction pattern of one image should fall on the first dark interval bet...

a criterion which characterizes the degree of roughness of a surface, for a given grazing angle of an electromagnetic wave according to the value of the quantity: where h is the average height of the surface irregularities, ? is the grazing angle relative to the average surface, ? is the wavelength NOTE - In practice, roughness is negligible and .....

An arbitrary (but useful) criterion for resolution. For a microscope, this is that the resolution is equal to 1.22·
λ/2·
NA, where λ is the wavelength of the light and NA is the
numerical aperture of an objective.

<microscopy> A criterion chosen by Lord Rayleigh to define the limit of resolution of a diffraction-limited optical instrument. It is the condition that arises when the centre of one diffraction pattern is superimposed with the first minimum of another diffraction pattern, produced by a point (or line) source equally bright as the first. For ...
