The MTS will simulate the optical characteristics of the JWST output beam in an environment similar to the flight conditions. The different functionalities of the MTS are briefly described and its current design, including the illumination and imaging subsystems, is presented.enginfo:eu-repo/semantics/article10.1117/12.5514531996-756Xinfo:eu-repo/semantics/restrictedAccess
