Radiation testing of thin optical coatings for space requires different approaches compared to bulk optical components or other material samples. In contrast to thicker samples, already particles of lower energy and thus lower range in the material will deposit high levels of dose in functional areas. In this paper we will discuss those differences and show ways to develop optimized test strategies.
