WebFWHM is Full Width Half Maximum. Take the maximum of your transmission peak, identify the points either side of the peak where the transmission is half the maximum, and the full width is the distance along the wavelength axis between those two points. It's just a way of measuring the width of a peak. The physical meaning will depend on the ... WebThe latter is called the full width at half maximum(FWHM). Valley definition[edit] The valley definition defines ΔM as the closest spacing of two peaks of equal intensity with the valley (lowest value of signal) between them less than a specified fraction of the peak height. Typical values are 10% or 50%.

In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value.
