Half-wave spectral width is defined as the relative spectral energy distribution curve, corresponding to the two-and-a-half maximum intensity at the wavelength difference, it marks the spectral purity, but. It is defined as the wavelength at which the spectral distribution or line reaches its largest value. This wavelength defines the position of the spectral center of mass. The center wavelength is defined as. The full width at half maximum (FWHM; bandwidth) of a typical quasi-monochromatic LED varies between 20 and 70 nanometers (see Figure 1), which is similar in size to the excitation bandwidth of. Full-Width-Half-Max: Usually abbreviated as FWHM. Used most commonly when discussing beam angle or spectral bandwidth. In both cases it refers to the distance from 50% to 50% point, or 3db to 3db.
