Abstract
A method controls fabrication of a multi-layered integrated computational element designed to have a target optical spectrum. A transfer function is generated relating a blue wavelength, shift between an as-annealed optical spectrum and an as-fabricated optical spectrum of a first integrated computational element at a standard temperature. Using the transfer function, an initial compensating red shift is incorporated into a second integrated computational element such that the as-annealed optical spectrum of the second integrated computational element matches the target optical spectrum.
