Abstract

We describe the concept, limitations, design, and application of a broadband antireflection coating for germanium which does not use zinc sulfide or zinc selenide. These materials have some undesirable working properties in production and it can be shown that their index of refraction limits the spectral performance which can be achieved. A design using only germanium and thorium fluoride can meet a broad range of requirements when stress and environmental durability are kept under control.
