Centre wavelength
The centre wavelength is the power-weighted mean wavelength: And the total power is: where is the power spectral density, for example in W/nm. The above integrals theoretically extend over the entire spectrum, however it is usually sufficient to perform the integral over the spectrum where the spectral density is higher than a fraction of its maximum.
