WebWhen using the Keplerian or Galilean designs in laser beam expander applications, it is important to be able to calculate the output beam divergence. This determines the deviation from a perfectly collimated source. The beam divergence is dependent on the diameters of the input and output laser beams. WebThe HDD cannot be measured by laser diffraction, but the median of the peak size may be obtained by using further calculations. Therefore, the recalculation of the particle size distribution from intensity- to volume-based and then the calculation of the volume-weighted D-values are necessary for a reasonable comparison..
