A coupling device for axially coupling together the ends of very thin optical fibres, fixed in one coupling house each, for achieving an optical connection between the fibres, and comprising a lens system arranged in each coupling house consisting a lens body, a glass body, a space for an optically means, and a fibre contact coaxially arranged thereto, shaped as a holder for at least one fibre. The focal point of the lens body is arranged to coincidence with the end surface of the fibre contact facing the lens body. The glass body is arranged to constitute a rear limit for the lens system, and is axially adjustable so that the focal point of the lens system, for the wavelength used, coincidences with the rear end surface of the lens system and the glass body, and thereby the end surface of the fibre contact facing the lens system. |
