The upgraded version of the Interferometric BIdimensional Spectrometer - IBIS 2.0 of the Italian National Institute for Astrophysics (INAF) - which was operated at the Dunn Solar Telescope of the National Solar Observatory from 2003 to 2019, shall be installed at the THEMIS telescope during the fall of 2025.

This will mark the return of the Italian involvement in the THEMIS telescope. The spectral imaging capacities of IBIS 2.0 shall benefit from the THEMIS Adaptive Optics and will synergically complete the existing spectro-polarimetric instrumentation of THEMIS.
