Rayleigh scattering size limit
WebRayleigh criterion equation. In the Rayleigh criterion equation, CD is the critical dimension, or smallest possible feature size, and λ is the wavelength of light used. NA is the numerical … WebFeb 7, 2015 · When the size of a structure under a conventional optical microscope is slightly smaller than the Rayleigh limit, the intensity decreases rapidly to the point of it becoming no longer visible. This can be described in terms of Rayleigh scattering, in which the object size d < < λ and the intensity of the scattered light decreases as a function of d 6 .
