THEMIS at short 90 cm Ø Ritchey-Chrétien telescope f/17 at F1 focus
Polarimetric analysis at F1 (no instrumental polarization at 2-3×10-5 level) 3 post-focal instruments: MTR: Multiline spectropolarimetry. High-res double spectrograph allowing up to 10 (6) spectral domains observed simultaneously from 4000 – Å MSDP: Spectro-imager. IPM: Tunable imaging filter (UBF + etalon). High-spectral resolution (90 mÅ)
