Abstract

An optical fibre (14) is optically coupled to an optically active element (13), for example a light source. In order to achieve optimum coupling, the end portion of the fibre (14) is carefully adjusted in relation to said element (13) in three dimensions. The end of the fibre is provided with a sleeve (15) slidably mounted in a bushing (17). The bushing is provided with a flange (18) which is adjustably pressed against a surface (12) on a mounting base (11) which is perpendicular to the axis of the sleeve (15). The mounting base (11) also carries the optically active element (13) near the end of the fibre (14). After the sleeve (15) and the bushing (17) respectively are adjusted so that maximum coupling is obtained between the fibre and the optical element the sleeve (15), bushing (17) and mounting base (11) are fixed together by introducing a highly fluid, quick-setting glue, preferably a cyanoacrylate, between the sleeve (15) and the bushing (17) and between the bushing (17) and the mounting base (11).
