Paper Abstract

In this contribution, we describe the optical design of UVESP, an efficient instrument designed for mid resolution (30.000) spectropolarimetric observations in the 119-888nm wavelength range. Spectropolarimetry introduces challenging constraints in the image quality of the echellé design that are addressed via the introduction special optical elements. UVESP design is significantly optimized with respect to previous similar instruments, such as the spectrograph proposed for the UVMag mission, and it is the current baseline spectropolarimeter for the ARAGO mission.
