Wide-field double nematic LCVRs address the high angular sensitivity of nematic LCVRs at some voltage regimes. We present a work in which wide-field LCVRs were designed and built, which are suitable for wide-field-of-view instruments such as polarimetric coronagraphs. A detailed model of their angular acceptance was made, and we validated this technology for space environmental conditions, including a campaign studying the effects of gamma, proton irradiation, vibration and shock, thermo-vacuum and ultraviolet radiation. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).enghttps://v2.sherpa.ac.uk/id/publication/issn/0277-786Xinfo:eu-repo/semantics/conferencePaperAngular acceptanceAngular sensitivitycoronagraphsDetailed modelsEnvironmental conditionsGround basedPolarimeters and ellipsometersPolarization modulatorsSpace-basedVariable retarderWide-fieldEllipsometryInstrumentsPolarimetersProton irradiationRadiation effectsSpace applicationsUltraviolet radiationVacuum applicationsLiquids2021-04-12Uribe-Patarroyo, N.Alvarez-Herrero, A.García Parejo, P.Vargas, J.Heredero, R.L.Restrepo, R.Martínez Pillet, V.Del Toro Iniesta, J.C.López, A.Fineschi, S.Capobianco, G.Georges, M.López, M.Boer, G.Manolis, I.10.1117/12.904919
