The invention relates to a coupling device for coupling and/or decoupling of electromagnetic waves into or from a transmitter or receiver element, for example, from a light wave guide, comprising a reflecting surface (8). According to the invention, the above coupling device, permitting the lowest possible losses on projecting and guiding light in the smallest space, whilst being easy to adjust and cheap to produce, may be provided whereby the reflecting surface (8) is curved. The invention further relates to a method for the production of a coupling device, whereby the reflecting surface (8) is produced as part of a rotational surface with a conical section as generating envelope. |
