A new bending‐magnet beamline with a 2.5 m normal‐incidence monochromator has been constructed to serve with a light source in the visible–vacuum‐ultraviolet region for photoluminescence, transmission and reflection spectroscopies of solids at the UVSOR‐III 750 MeV synchrotron radiation light source. The aim is to pave the way to establishing a beamline with high photon flux, high brilliance, high energy‐resolution, high linear‐polarization and low higher‐order light. To obtain high photon flux and brilliance, the acceptance angle of the bending‐magnet radiation was designed to be 40 mrad (H) × 14 mrad (V) and the post‐mirror system employed Kirkpatrick–Baez optics. The incidence angle of the incoming light to the optical elements, except to the gratings, was set to a grazing angle in order to keep a degree of linear polarization. For achieving high energy‐resolution, an off‐plane Eagle‐type monochromator was adopted. Higher‐order unwanted light in the energy range below ∼11 eV was suppressed to be less than 0.1%.
