X-ray-reflective mirrors are disclosed, each including a thermal-transfer device that conducts heat (caused by absorption by the mirror of incident X-ray radiation) away from the mirror without imparting stress to the mirror. As a result, each such mirror exhibits, compared to conventional X-ray-reflective mirrors, reduced deformation and greater thermal stability during use of the mirror. A typical X-ray-reflective mirror is formed from a mirror substrate and has an "effective region" on which X-rays are incident. At least the effective region includes an X-ray-reflective coating (e.g., multilayer coating). Attached to the mirror are thermal-transfer members that function to conduct heat away from the mirror. Each thermal-transfer member is attached to a respective location outside the effective region of the mirror so as not to obstruct reflection of X-rays incident to the effective region. Distal ends of the thermal-transfer members are connected to a suitable cooling mechanism. The thermal-transfer members are configured and dimensioned so as not to impart any significant stress to the mirror.
