Optical layouts for large infrared beamline apertures

Synchrotron infrared beamlines are powerful tools to perform spectroscopy on microscopic length scales but require working with high intensities which are obtained using large horizontal beamline apertures. Most of the infrared beamlines use a single toroid shaped mirror to conjointly focus both the vertical and the horizontal source emission but generate for large apertures distorted images due to the optical aberrations produced by the depth and the circular shape of the source. In this presentation, we will describe a new optical layout consisting in two optimized shape mirrors, focusing respectively the vertical and the horizontal source emission, and providing low aberration beams for large horizontal apertures. The results obtained on the SLRI (Thai) and LNLS (Brazilian) Infrared beamlines, which use this new approach, will be analyzed.
