title: Design method for multilayer interference filters.
abstract: In this paper expressions for the transmittance and the reflectance of a system consisting of a spacer surrounded by two multilayer stacks are presented. These expressions provide a general approach for the design of multilayer coatings. High- and low-transmittance bands and a narrowband in the transmittance spectrum of multilayer stacks with unequal designed wavelengths are reported.
