Thin film coated mirrors enable pioneering observations of X-rays and soft gamma rays. The performance of the reflective mirrors is key in expanding knowledge of the hot and energetic Universe. A critical part of maturing the optics technology is firstly, to establish a smooth surface and interface of the selected materials and, secondly, to obtain an in-depth understanding of the contamination in the thin films and ultimately, to ensure long-term stability. The aim of this study is to investigate the chemical composition, roughness and stability of boron carbide and iridium thin films and the effects of nitrogen incorporation.
