ESPRESSO achieves First Light: the front-end structure
“ESPRESSO deploys three major technological advances with respect to its predecessors: a Laser Frequency Comb for optimum wavelength calibration - Nobel prize winning technology in 2005 - as well as a novel system to fold the beam inside the spectrograph to diminish the instrument size and with this its complexity, and two 9cm x 9cm CCD, among the largest monolithic CCDs in the world,” adds Lo Curto.
Simulation facility Elsewhere, a new simulation facility at the Planetary Spectroscopy Laboratory (PSL) of the German Aerospace Centre (DLR) has recently been launched. It will be used mainly for the collection of compositional data for the surface of Venus – particularly for taking Venus-analogue emissivity measurements from 0.7 to 1.5 µm over the whole Venus surface temperature range. Te PSL is located in a temperature-
controlled room and uses two Bruker Vertex 80V spectrometers located on an optical table equipped with external chambers for emissivity measurement. Te instrument used for the new Venus
