Rayleigh criterion for resolving power

Resolving power is the ability of an imaging device to separate (i.e., to see as distinct) points of an object that are located at a small angular distance or it is the power of an optical instrument to separate far away objects, that are close together, into individual images. The term resolution or minimum resolvable distance is the minimum distance between distinguishable objects in an image, although the term is loosely used by many users of microscopes and telescopes to descr… WebIf λ is the wavelength of light, D the diameter of the telescope objective, and θ the angle subtended by the point object at the objective, the limit of resolution of the telescope is …
