An un-obscured four spherical mirrors based collimator as a tradeoff solution for the Optical Ground Support Equipment (OGSE) of the High Resolution Camera (HRIC) of Simbio-Sys

摘要

The authors present the tradeoff and the merit criteria that lead to the selection of the M. Brunn [1]"un obscured four mirrors based telescope" as the collimator of the Optical Ground Support Equipment in theframe of the Assembly Integration and Verification (AIV) activities forecast for the optical characterization ofthe High Resolution Camera (HRIC) on board of the Simbio-sys mission to Mercury, instrument currentlyunder development and manufacturing at Selex Galileo (SG) facilities in its Florence site. Several opticalconfigurations have been accounted for the design and manufacturing of the three meters focal length,diffraction limited and wide field of view (0.4X0.6 degs) toolkit. From the classical un obscured systems suchas the aspheric solution based onto two hyperbolic mirror, working under an f - number of 13.6, the Brunnsolution revealed excellent optical quality free from coma, astigmatism and spherical aberration accomplishedby an ultra compact design in within a volume of 1.2x1.0 x0.5 cubic meters and other basic advantages suchas the relative easy way in aligning and manufacturing the mirrors.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
