Abstract

A device for connecting first and second light guides to an external part. Each of the light guides extend into a housing which includes a converging aspheric plano-convex lens. The lenses are mounted so that the focal point of the lens is located at the end surface of the light guide and the aspheric surface of the lens faces the light guide. The planar surface of the lens forms a coupling surface to support immersion fluid for connection to the external part.
