Total reflection mirror and crystal monochromator are presented as two major optical elements in synchrotron radiation beamline. Reflectivity, typical X-ray mirrors used at SPring-8 beamlines, and sagittal and tangential focusing are shown for total reflection mirror. Energy range and energy resolution using crystal monochromator, geometry and mechanism for double-crystal monochromator, and cooling of first crystal from high heat load are shown briefly with the examples of SPring-8 standard beamlines. Photon flux through the beamline optics is also estimated with the effective band-width of monochromator.
