Physical and infrared optical properties of mixed SrF_2-CaF_2 thin films
SrF_2-CaF_2混合物薄膜的物理及红外光学特性研究

The mixed SrF2-CaF2thin films with the same thickness were deposited by the techniques of resistant evaporation and electron beam evaporation respectively.The physical and infrared optical properties of the thin films were investigated.The optical constants in the infrared region were determined quantitatively which fills the gap of these data.At the same time,we provided a method to obtain gradient index films.We also used the mixed SrF2-CaF2 with a proportion of 1:1 as the lower index material to deposit ...
