Full Width Half Maximum (FWHM) of a transmission spectrum

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 ...
