ABSTRACT:
The present invention relates to a contact device intended for obtaining optical connection between an opto-component (1) and an optical fiber (2). The contact device includes a first contact-part (3) in which the opto-component is fixedly mounted, and a second contact-part (4) in which the optical fiber is fixedly mounted. The contact-parts (3, 4) present mutually opposing openings (8, 15) which extend respectively from the opto-component (1) and the fiber (2), and the contact-parts are secured together in a manner to obtain the best light-transmission properties. The contact-parts (3, 4) have mutually abutting and mutually complementary spherical surfaces (9, 19), which enable the contact-parts to be rotated relative to one another about their center axes and also to be angled in relation to one another. The openings (8, 15) dissect spherical segments in the abutment surfaces (5) of the contact-parts.
