We present the NIR spectrograph of the Son Of XShooter (SOXS) instrument
for the ESO-NTT telescope at La Silla (Chile). SOXS is a R~4,500 mean
resolution spectrograph, with a simultaneously coverage from about 0.35
to 2.00 μm. It will be mounted at the Nasmyth focus of the NTT. The two
UV-VIS-NIR wavelength ranges will be covered by two separated arms. The
NIR spectrograph is a fully criogenic echelle-dispersed spectrograph,
working in the range 0.80- 2.00 μm, equipped with an Hawaii H2RG IR
array from Teledyne, working at 40 K. The spectrograph will be cooled
down to about 150 K, to lower the thermal background, and equipped with a
thermal filter to block any thermal radiation above 2.0 μm. In this
poster we will show the main characteristics of the instrument along
with the expected performances at the telescope.
