Simplified Design Equations for an Optical Quarter-Wave Stack Reflection Filter.

Abstract

Formulas are presented which describe the major operational parameters of the high-rejection, narrow bandwidth, quarter wave stack optical interference filter. Mathematical equivalence is demonstrated between the results of the development of two prominent, present day theoreticians. To facilitate the understanding of the utility of the simplified equations, a practical design problem has been analyzed. Further areas for application of the equations are suggested. Keywords: Optical filters; Interference filters; Quarter wave stack; Periodic media; Thin films.
