In particular, a set of fully representative filters has been manufactured by Ametek/Canatu using the high density CNT pellicle, bare and coated with aluminum, attached to Au plated BeCu meshes, and mounted onto aluminum frames. This document provides a brief description of test procedure, test equipment, and schedule for each proposed characterization methodology to be performed within task 5 of the contract. For more technical details on the equipment and accuracy of the test methodology we sometimes address the previous technical notes TN2 and TN6.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
