An overview of the optical design for the SOXS spectrograph is
presented. SOXS (Son Of X-Shooter) is the new wideband, medium
resolution (R>4500) spectrograph for the ESO 3.58m NTT telescope
expected to start observations in 2021 at La Silla. The spectroscopic
capabilities of SOXS are assured by two different arms. The UV-VIS
(350-850 nm) arm is based on a novel concept that adopts the use of 4
ion-etched high efficiency transmission gratings. The NIR (800- 2000 nm)
arm adopts the ‘4C’ design (Collimator Correction of Camera Chromatism)
successfully applied in X-Shooter. Other optical sub-systems are the
imaging Acquisition Camera, the Calibration Unit and a pre-slit Common
Path. We describe the optical design of the five sub-systems and report
their performance in terms of spectral format, throughput and optical
quality. This work is part of a series of contributions1-9 describing the SOXS design and properties as it is about to face the Final Design Review.
