Paper Abstract

Although high energy laser systems require low scattering optical surfaces, conical optical elements have intrinsically high scattering surfaces due to nonconventional fabrication techniques. The scatter-ing behavior of diamond-turned optical surfaces with steep curvatures can be characterized by an equivalent bidirectional reflectance distribu-tion function (BRDF). Existing computer programs can be used to perform a detailed stray radiation analysis of the optical system and to establish optical component scattering tolerances. These scattering tolerances are then translated into surface finish specification through a simplified theory of surface scatter phenomena.
