WebDepending on the particle characteristics and requirements, two common analysis theories are applied: the Fraunhofer theory for larger particles whose optical parameters are not known and the Mie theory for smallest particles with known optical parameters. Back to FRITSCH Knowledge OVERVIEW Overview Static Light Scattering Dynamic Image … WebIn contrast to Mie theory only the Fraunhofer model does not require knowledge of optical properties. Hence, solely Fraunhofer is applicable to mixtures of different materials and shapes. With laser diffraction the determined particle size always refers to the equivalent diameter of a sphere sharing the same diffraction pattern. WebIn a word, the Fraunhofer diffraction theory is one of the approximate expressions of the Mie scattering theory. This approximate expression can be used only when the following two conditions are satisfied: The particle size is relatively large (at least, 10 times the laser wavelength) The scattering angle is small (30° or less) In a range in ... teka teki paling bodoh
