Imaging spectroscopy is intended to be coupled with adaptive optics (AO) on large telescopes, such as EST, in order to produce high spatial and temporal resolution measurements of velocities and magnetic fields upon a 2D FOV. We propose a high spectral resolution slicer (30 mÅ typical) for the Multichannel Subtractive Double Pass (MSDP) of the future European Solar Telescope (EST), using a new generation slicer for thin photospheric lines such as FeI (56 channels, 0.13 mm step) which will benefit of AO and existing polarimeters. The aim is to reconstitute cubes of instantaneous data (X, Y, lambda) at high cadence, allowing the study of the photospheric dynamics and magnetic fields.
