Abstract:Two multilayer antireflection coatings have been designed, prepared and characterized for a 1 mm thick Ge optical window in 3.25-5.25 t band for optical and electro-optical application. Ta2O5 and TiO2 have been used as high index materials along with SiO2 as low index material. The prepared multilayer structures have been characterized optically and structurally using spectrophotometery, atomic force microscopy (AFM), x-ray diffraction (XRD), and scanning electron microscopy (SEM). Post deposition annealing of… Show more
