The high strength-to-weight ratio and thermal diffusivity of beryllium are very attractive to the optical system designer for many critical applications. In order to realize the potential advantages of beryllium, it is necessary to have mirror blanks figured to optical tolerances which are also dimensionally stable over the life of the system. As part of a program to improve the dimensional stability of beryllium, we have cataloged the properties of both Kanigen-coated and bare beryllium mirrors. The results presented in this report indicate the bare beryllium is to be preferred over Kanigen-coated beryllium for precision optical surfaces.
铍的高强度重量比和热扩散率对许多关键应用的光学系统设计师极具吸引力。为了实现铍的潜在优势，有必要制造出符合光学公差且在系统使用寿命内尺寸稳定的镜坯。作为提高铍尺寸稳定性计划的一部分，我们已将镀镍磷合金和裸铍镜的特性编目。本报告中呈现的结果表明，对于精密光学表面，裸铍比镀镍磷合金铍更可取。
