Fwhm full width half maximum
WebMar 31, 2024 · For Gaussian beam size measurements, OpticStudio uses the 1/e 2 half-width point, which means the intensity has fallen to about 13.5% of the peak. However, often times manufacturer’s data sheets provide only Full Width Half Maximum (FWHM) measurements and not 1/e 2 half-widths. The relationship between the FWHM and 1/e 2 … WebThe significance of as a measure of the distribution width is clearly seen. As can be calculated from (19), the standard deviation corresponds to the half width of the peak at about 60% of the full height. In some applications, however, the full width at half maximum (FWHM) is often used instead.
