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.engCoronagraphsLiquid-Crystal variable retardersSpace applicationsinfo:eu-repo/semantics/article10.1117/12.9049191996-756Xinfo:eu-repo/semantics/restrictedAccess
