A new beamline for an infrared (IR) microspectroscopy is under construction in the SR center of Ritsumeikan University. We designed an optical system which collects synchrotron radiation (SR) photons by installing one toroidal mirror and two plane mirrors in the storage ring chamber. As a result, the acceptance angle can be widened up to 250mrad in horizontal and 63mrad in vertical. Our aim is to develop an IR microspectroscopy beamline with spatial resolution of the order of sub micron from mid-IR to far-IR. In this paper, we present a designed optical system of IR microspectroscopy and the results of ray-tracing.
