6 December 1993 Effect of space radiations on optical filters
Author Affiliations +
A multilayer filter, that will fly on the SOHO mission, has been designed to resist 3 - 4 major solar flares. This paper reports on the effects of the simulated solar flare on the glasses and filters. For the color filter glasses, transmittance drops could be up to 18% at 500 nm, for the 7-year simulated test, while for the heat absorbing glasses it was a few %. The filter transmittance dropped relatively by 2.6% and 15%, for the 2-year and 7- year doses, respectively. In most cases the filter profiles were slightly affected. The effect of the irradiations on the coatings, the adhesive and the glasses is discussed. Guidelines for minimizing effect of irradiations on coatings and glasses are given.
