Abstract

Remote sampling systems using a flexible optical fiber are necessary for various applications of the Raman spectroscopy in biomedicine. Recently the use of a hollow optical fiber as a Raman probe has been proposed [1]. Because the hollow optical fiber, which consists of a thin glass capillary tubing inner-coated with a silver film, generates no fiber background, the filter-free Raman probe with a single fiber can be realized.
