We introduce a novel nonlinear optical microscope which provides interface specific, chemically and
structurally resolved infrared information with the improved spatial resolution limit of a visible light
microscope. High impact on the investigation of a large variety of interfaces is expected. Here, the microscope
is applied in a dewetting study.
Second‐harmonic microscopy—an application of which is presented in the previous article—is a fast quantitative technique for the imaging of interfaces such as that in the Figure. The theory of the technique, which is based on the generation of second‐harmonic light specifically at surfaces or interfaces due to their lack of centrosymmetry, is outlined and the interpretation of the results discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
