Paper Abstract

This paper reports the development of high volume fraction SiC P / Al composite-bismuthate glass multilayer films optics Au-mirror with high reflectivity in a wavelength range of 760 to 1000 nm. Multilayer films were fabricated using an radio frequency-magnetron sputtering deposition system. The measured reflectivity of Ta 2 O 5 / SiO 2 / Au / Cr metal plus dielectric films optics Au-mirror could reach up to 97 % . Then, on the basis of experiments, a Φ 75 - mm high volume fraction SiC P / Al composite-bismuthate glass multilayer optical Au-mirror for a wavelength range of 760 to 1000 nm was manufactured. The tested results indicate that a peak-to-valley value of 0.854 λ ( λ = 632.8    nm ) was achieved on the Au-mirror surface, and the slope deviation error for the flat surface was lower than 0.153 λ root mean square. The surface roughness of Ta
