MA_MISS GSE illumination system + EQM-SAC + FM ROD#2 – PRELIMINARY CHARACTERIZATION and SPECTRAL PERFORMANCES TESTS

Abstract

This document reports on the Ma_Miss EQM SAC and FM ROD#2 preliminary power/optical and spectral characterization. Optical transmittance tests have been performed coupling the Silicon photodiode with the Ma_Miss output C1 fiber + EQM SAC (setup #1) and with the output of FM ROD#2, acquiring signal in two different configurations (setup #2 and setup #3). Spectral performances tests have been carried out by coupling the AVANTES spectro-photometers with the output fiber of FM ROD#2 (setup #4). In addition to absolute radiometric measurements performed with Si photodiode, measurements with a spectrometer are essential in order to characterize the spectral behavior of all instrument subsystems. Such measurements must be intended as preliminary, and more systematic spectral analyses should be planned in the next future.
