Paper Abstract
Glass and metallic image slicer breadboards have been designed, manufactured and tested for MUSE (Multi Unit
Spectroscopic Explorer) instrument, a second generation integral field spectrograph developed for the European
Southern Observatory (ESO) for the VLT. MUSE is operating in the visible and near IR wavelength range (0.465-0.93
μm) and is composed of 24 identical integral field units; each one incorporates an advanced image slicer associated with
a classical spectrograph.
This presentation describes the optical design, the manufacturing, component test results (shape, roughness, Bidirectional
Reflection Distribution Function - BRDF) and overall system performance (image quality, alignment) of two image
slicer breadboards. The first one is made of Zerodur and uses individual optical components polished by a classical
method and assembled together by molecular adhesion. This breadboard is a combination of mirrors and mini-lens
arrays. The second one is made of metal (copper or invar) using monolithic or segmented optical elements and state-ofthe-
art diamond-turning machines. It is composed of two sets of reflective mirrors.
We will then conclude with a comparison between these two different breadboards by choosing the most suitable
solution for the 24 MUSE image slicers.
