The need for stray light control is pervasive, throughout multiple NASA missions. Among the applications we have considered for the aligned arrays, some are 'Aerospace only." These include: IR detector cold shields, coronagraph baffles, space-borne optical systems, spectro-radiometers, cryogenic radiometers, occulters, sharp edged diaphragms & blades, and passive thermal control coatings w/ tailored absorptance/emittance. We expect that these coatings, once advanced to a sufficient TRL, will be able to provide significant enhancements to a number of missions. The Wide Field Infrared Survey Telescope (WFIRST) and New Worlds Technology Development Program (NWTP) are two target programs where we recognize the coating could have a dramatic impact on the performance of the optical train.
