Rayleigh depth of focus
WebThe Rayleigh length is defined as the distance for which the beam radius is smaller or equal to √2 times the radius at the waist. So, when a focal length is small compared to the incident beam size, the depth of field tends to be small and vice-versa. WebNov 13, 2015 · The definition of focus is somewhat subjective, but a standard depth of field "unit" is often defined as half the axial Rayleigh unit: d = lh/(NA) 2. Another criterion that is …
