Paper Abstract

Any future solar telescope project should incorporate an imaging spectrometer. For the future EST (European Solar Telescope) the Observatoire de Paris offers an imaging spectro-porarimetry instrument: a new generation of MSDP. To validate this new generation, we develop a beam slicer prototype that will be tested and validated on optical bench and on existing telescopes. The study assesses the performance gain of such an instrument on a solar 4m class telescope. We present opto-mechanical solutions of a new beam splitter and its implementation in EST.
