The infrared microspectroscopy beamline (MIRAS), dedicated to infrared microspectroscopy, is a valuable tool to identify the chemical composition of materials at the molecular level. The aim of this beamline is to allow infrared microspectroscopy and imaging, using a Fourier Transform interferometer with capacity to address the present and the future requirements of the scientific community. The scientific applications of MIRAS is covering a wide range of research fields, including surface and material science, biochemistry, microanalysis, archaeology, geology, cell biology, biomedical diagnostics, environmental science, etc.

MIRAS is dedicated to infrared microspectroscopy, with the aim to deliver world class performance in terms of a bright and highly stable photon beam. The beamline will provide ALBA users with a modern infrared microspectroscopy facility covering a wavelength range from 0.4 to 100 µm with a spectral region optimized for investigation between 2.5-14 µm. The design of the beamline optimizes performance in the mid-IR range and will give significantly enhanced efficiency, compared to a conventional source, in both far-IR and mid-IR regions.
