A beamline for linearly polarized light radiation from an undulator is being commissioned at DELTA, an University synchrotron facility. The electron beam in the undulator as a radiation source is mapped by the first optical element onto an intermediate focus. Mirror M1 has a large acceptance angle in order to provide a stable performance if small electron beam displacements occur. The intermediate focus is demagnified onto the sample providing a focus spot size of 70 x 30{mu}m2. The PGM (Plane Grating Monochromator) based beamline works with collimated light allowing a flexible use of the monochromator. Depending on user demands, it can be operated by at high spectral resolution, high flux mode, or at high order suppression.
