Apertureless near-field scanning raman microscopy using reflection scattering geometry

摘要

An apertureless near-field scanning Raman microscope using reflection geometry. A laser beam focused to a small spot size on a sample onto which a silver coated metal probe is positioned. With this arrangement, it is possible to obtain enhanced near-field spectroscopy using reflection geometry. Near-field spectroscopic mapping can be done in a short time without extensive sample preparation.
