本文介绍了金刚石车削各种单晶和多晶红外窗口材料表面的结果，包括Ge、caf2、mgf2、srf2、KCl和GaAs。这些表面是由一种先进的空气轴承钻石车床获得的，该机床最近在海军武器中心投入使用。所进行的表面表征包括广泛的光学和表面物理检查，包括散射和吸收光的分析，以及通过金刚石轮廓术、相对比干涉（Nomarski）和扫描电子显微镜进行的表面微观形貌检查。这些数据与先前的结果进行了比较，并与海军武器中心金刚石车床的特性和加工参数有关。本次会议的一篇论文讨论了这些表面的抗激光损伤性及其在激光应用中的应用。
This paper presents the results of the diamond turning of surfaces of a wide range of single-crystal and polycrystalline infrared window materials, including Ge, CaF 2 , MgF 2 , SrF 2 , KCl, and GaAs. These surfaces were obtained from an advanced air-bearing, diamond-turning machine recently brought to an operational state at the Naval Weapons Center. The surface characterization performed includes a wide range of optical and surface physical examination including an analysis of scattered and absorbed light, and a surface micro-topographic examination by diamond profilometry, phase contrast interference (Nomarski), and scanning electron microscopy. These data are compared with earlier results and are related to the characteristics of the Naval Weapons Center diamond-turning machine and to the machining parameters. A companion paper at this conference discusses the laser damage resistance of these surfaces with implications for their use in laser applications.
