New Christiansen filters

Abstract

A number of new optical filters that are based on the well-known Christiansen effect of scattering light in a heterogeneous medium have been fabricated. In addition to the conventional solid-in-liquid systems, we fabricated some solid-in-solid filters, which we refer to as solid Christiansen filters. Here we report on their fabrication, performance, and applications. From our experiments we have also derived the dispersion curve for a liquid styrene monomer in the visible region.
