Abstract
An optical head for equipping the distal end of a flexible optical fiber bundle, designed to be urged into contact with an analyzing surface and including optical elements for focusing an excitation signal into a so-called excitation focal point located at a specific depth beneath the analyzing surface and for sampling a signal backscattered by the excitation focal point which is carried back by the fiber bundle. The head includes an optics-holder tube wherein are inserted on one side the distal end portion of the fiber bundle and on the other optical elements, the latter including a plate placed in contact with the end of the fiber bundle whereof the index is close to that of the fiber core and a focusing optical block, an output window being further provided adapted to provide index adaptation so as to eliminate parasitic reflection occurring on the analyzing surface.
