    During the past 30 years of development of space optical instrumentation for such missions as METEOSAT, SPOT, HIPPARCOS and SILEX with ESA and CNS, Matra Marconi Space had conducted extensive studies on the behaviour of optical materials under irradiation such as quantifying transmission losses is optical glasses and measuing the dimensionsal stability of Zerodur as a substrate of mirror applications. Thanks to this background experience, MMS is conducting a study to define the approach for the gathering of a comprehensive data base to quantify these effects through the use of linear sensitivity coefficients. This follows recent investigations which have shown that the space radiation environment can affect not only transmission but also other characteristics of refractive optical materials in both classical and Cerium doped glass. A number of selected examples from specific MMS studies will be first shown. Then, the actual approach being taken to this problem, on the basis of already obtained results from preliminary performed ESTEC, will be presented.
