Abstract

Disclosed are improved integrated computational elements for use in optical computing devices. One integrated computational element includes an optical substrate, first and second pluralities of optical thin film layers alternatingly deposited on the optical substrate to form a thin film stack, wherein each optical thin film layer of the first plurality exhibits a first refractive index and each optical thin film layer of the second plurality exhibits a second refractive index different than the first refractive index, and at least one additional optical thin film layer arranged in or on the thin film stack and in optical communication with at least one of the optical thin film layers of the first and second pluralities, the at least one additional optical thin film layer exhibiting a third refractive index that is different than the first and second refractive indices.
