1. An optical interface for repeated non-permanent passive coupling of light between two optically transparent media, at least one of these media being solid comprising:

  • at least one reusable, shaped body of an optically transparent elastic material adapted to resiliently contact said solid media, said optically transparent elastic material having a refractive index matched to a refractive index of said solid media; and

    a support member for supporting said at least one reusable, shaped body;

    wherein said support member is at least partially optically transparent and said at least one reusable, shaped body is attached on at least one side to said support member to form at least one light coupling path.
