ABSTRACT:
Disclosed are methods for producing optical filters on a substrate. In particular, methods for producing microengineered optical filters for the ultraviolet/visible/infrared portions of the electromagnetic spectrum are disclosed, as well as a computer-based system and method for precisely matching predefined target transmission spectra using various coating materials whose spectra can be combined and weighted for the matching. In addition, methods for producing printed optical filters comprising multiple coating components to produce composite optical filters whose transmission spectra match predefined target filter spectrum specifications are disclosed, where the thickness and fill factor of each component coating is tailored, based on the weighting of each component coating transmission spectrum.
