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. WebMay 14, 2024 · If you are using Geant4 directly, you’re doing something wrong. Try these: setting the polarization of the incident optical photon as done in the extended/optical/OpNovice and OpNovice2 examples. use the G4OpticalPhysics constructor (see the examples) post the code where you define the Rayleigh interaction lengths.
WebMar 6, 2024 · The Rayleigh–Plesset equation can be derived entirely from first principles using the bubble radius as the dynamic parameter. Consider a spherical bubble with time-dependent radius [math]\displaystyle{ R(t) }[/math], where [math]\displaystyle{ t }[/math] is time.

The 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. Finally, M² corresponds to the quality factor.
