Optical elements consist of two part-elements arranged on three different planes, with part-elements and connecting-elements, basic part and two arms

摘要

Two part-elements (1,2) are positioned in relation to a shared adjusting axis and a re connected by at least three connecting elements (16) located on three different planes. Each connecting element is connected to one each of the two part-elements at a single point (6). The connecting elements, parallel with each plane, are highly rigid as a result of a geometrically produced high moment of resistance, and exert compressive force onto the part-element. Two arms (27) on the connecting elements lead into a basic part (26) The outer edges of the connecting elements are tapered (17).
