Abstract

Methods and apparatus for depth-resolved spectroscopy. A ball lens may be used to redirect light from a fiber-optic probe so that the light intersects the detection region of a collection probe in a specific depth layer of the specimen. A fiber-optic probe may comprise a collection fiber proximal to a central axis of a ball lens and a pair of illumination fibers distal to the central axis.
