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 … 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.
