Rayleigh length rp
http://www.lithoguru.com/scientist/litho_tutor/Tutor44%20(Feb%2004).pdf In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams.

WebAnother significant focus of this paper is the modelling of the bubble dynamics. The original RP equation (Rayleigh Reference Rayleigh 1917; Plesset Reference Plesset 1949) describes single-bubble behaviour in a quiescent incompressible liquid. WebFor a rough criterion, one can calculate the Rayleigh length based on the mode radius of the fundamental fiber mode. On the other hand, the far field is obtained in distances which are large compared with that Rayleigh …

WebFor microscopes, the resolving power is the inverse of the distance between two objects that can be just resolved. This is given by the famous Abbe’s criterion given by Ernst Abbe in 1873 as. d = λ 2 n s i n θ. Resolving power = 1 d = 2 n s i n θ λ. Where n is the refractive index of the medium separating object and aperture.
