Paper Abstract

We will present a design of a high contrast 3D spectrometer with the attractive characteristics to provide very low differential aberrations. This concept, very well suited for an instrument as planet finder, is based on our expertise in slicer unit. Thanks to a control of diffraction and roughness effect, this new concept will provide spectrograph entrance sub-slit with a high purity. Very low level of cross-talk signal is expected. Associated with the slicer unit, we will present a spectrograph concept allowing to guaranty a negligible level of differential aberration between wavelength in the spectrum.
