The TElecentric SOlar Spectrometer (TESOS) is a 2D tunable filtergraph installed at the Vacuum Tower Telescope of Teide Observatory (Tenerife, Spain). The instrument features a high spectral resolution (λ /Δ λ ˜ 250000 at 633 nm) and is capable of scanning solar lines over a broad wavelength range (430 - 700 nm). Together with the Kiepenheuer-Institute Adaptive Optics System (KAOS), it is able to achieve spatial resolutions of the order of 0.5 arcsec on a regular basis. Here we present the first spectropolarimetric observations of a sunspot and its immediate surroundings using TESOS. We describe the optical setup, characterize the performance of TESOS operated in the polarimetric mode, and investigate the appearance of the sunspot as seen in circular polarized light with an angular resolution better than 0.5 arcsec. Our results demonstrate the feasibility of using TESOS as a polarimeter, and may be of interest for the design of a TESOS-like multiple-etalon magnetograph for the 4-m NSO/Advanced Technology Solar Telescope.
