Rayleigh range formula
http://www.lithoguru.com/scientist/litho_tutor/Tutor44%20(Feb%2004).pdf WebTwice the Rayleigh range is called the confocal parameter (or depth-of-focus) and is a rough estimate of the collimation of a beam. As shown in the above equation, the beam size increases slowly with axial distance from the waist. As z >> zR, the beam size then increases linearly with z with a slope of W 0 /z R.

WebIn 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. Rayleigh length is particularly important when beams are modeled as Gaussian beams. For a Gaussian beam propagating in free space along the z-axis, the … north carolina rate bureau formsWebA classical law approximately describing the intensity of radiation emitted by a blackbody, derived by Rayleigh and Jeans by counting the number of standing wave modes in an enclosure. It corresponds to the Planck law in the case of small frequencies, in which case {h\nu/(kT)}\ll 1 allows the approximation e^{h\nu/(kT)}\approx 1 + {h\nu\over kT} +\ldots. north carolina rare lichensWebFor example, the Rayleigh Range of a Gaussian beam is the distance from the beam waist (in the propagation direction) where the beam radius is increased by a factor of √2 (which is equal to a doubling of the beam area).
