The Agilent/Keysight 10773A is a precision flatness mirror engineered for 90-degree laser beam redirection in optical measurement systems. It accommodates laser beam diameters up to 9 mm and delivers optical efficiency of 99% typical, 98% worst case, with 100% reflectance. Constructed from stainless steel 416 housing and optical grade glass optics bonded with low volatility vacuum-grade adhesives, this mirror provides reliable beam path manipulation for flatness and surface plate calibration applications within the Keysight 5530 Laser Calibration System.
