Abstract

An expanded beam optical connector comprises a spherical lens 11 and a diverging plano-concave lens 7 which are retained in a frusto-conical portion 2 of a through-cavity of the connector body 1. The through-cavity has a cylindrical portion 3 which supports the end portion of an optical fibre 27. The lens 11 and 7 are in direct mutual contact. The spherical lens 11 seats against the wall of the frusto-conical portion 2 and the diverging lens 7 is accommodated in a cylindrical recess 6 of an annular support member 5 which is elastically deformable radially and is also seated in the frusto-conical portion 2. During assembly of the connector lens 11, on engaging the circular edge 12 of lens 7, causes radial movement of lens 7 until the whole of edge 12 is contacted by lens 11 until the axes of both lenses coincide.
