    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.

    Abstract: Elle est prévue pour équiper l'extrémité distale d'un faisceau de fibres optiques souples (2), destinée à venir au contact d'une surface d'analyse et comprenant des moyens optiques (3) pour focaliser un signal d'excitation en un point focal dit d'excitation situé à une profondeur donnée sous la surface d'analyse et pour prélever un signal rétroémis par le point focal d'excitation qui est véhiculé en retour par ledit faisceau de fibres. Elle est caractérisée par un tube porte-optique (4) au sein duquel sont introduits d'un côté la partie terminale distale (1) du faisceau de fibres (2) et de l'autre les moyens optiques, ces derniers comprenant une lame (21) placée au contact de l'extrémité (14) du faisceau de fibres dont l'indice est proche de celui du coeur des fibres et un bloc optique de focalisation (3), un hublot de sortie (30) étant en outre prévu adapté à réaliser une adaptation d'indice de manière à s'affranchir de la réflexion parasite s'opérant sur la surface d'analyse.
