WebJan 19, 2024 · The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R = 1.22λ/(NA obj + NA cond) where λ is the wavelength of light used to image a specimen. NA obj is the NA of the objective. NAcond is the NA of the condenser. The value ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel Functions.

WebRayleigh scattering, or light scattered from particles smaller than the wavelength of light, was explored by Lord Rayleigh almost 150 years ago but has not been widely used as a significant spectrographic technique because of the difficulty of measuring the scattering efficiency from a single nanoscale object.As shown by Lord Rayleigh, the scattering … flame keepers casinoWebOct 1, 2000 · This criterion relies on finding the maximum local Rayleigh number in the mush, where the ratio of the driving buoyancy force to the retarding frictional force is the largest.
