A method to optimize the notches of water‐cooled white‐beam mirrors over the entire photon energy range is proposed. A theoretical method is used to quantitatively evaluate the influence of the thermal load on the thermal deformation of a mirror. The result of theoretical calculations and finite‐element analysis are consistent, which proves the feasibility of the method. The root mean square of the curvatures of the thermal deformation of the white‐beam mirror over the entire photon energy range can be minimized. This method greatly simplifies the design work of water‐cooled white‐beam mirrors.
