Abstract: THEMIS, the French 1-m class solar telescope located at Teide Observatory, has benefited from profound renovations and modification of its light path over the last 10 years. Thanks to a state-of-the art solar adaptive optics, THEMIS observations can now reach THEMIS theoretical diffraction limit at 0.15”, enabling to resolve details on the scale of 100 km on the Sun. In the last two years, THEMIS spectro-polarimetric mode has also been renewed and successfully producing polarization-calibration free Stokes-parameters data-cubes. Unprecedented observations are thus now being obtained. During the spring of 2026, a new synergic spectro-imager, the Italian “Interferometric BIdimensional Spectrometer (IBIS)” will be installed and commissioned at THEMIS. All these recent developments opens new possibilities of support observations for several Solar Orbiter Observing Programs, as well as for IRIS and ADITYA.
