Abstract
For the remote detection of chiral amino acids to be feasible, it is required to develop a high sensitivity spectropolarimeter susceptible to detect the signature of the Optical Rotatory Dispersion (ORD) produced by alanine in the 160-200 nm spectral range. This instrument is part of the payload of the Ultraviolet Researcher to Investigate the Emergence of Life (URIEL), a small size (50 cm primary) space telescope designed to carry out low dispersion (600-1,000) UV spectropolarimetry in the 140-350 nm spectral range. In this contribution, we describe the design of the spectropolarimeter.
