Abstract
Holding devices adapted for holding edged optical elements, manufacturing systems including such holding devices, and a corresponding method for manufacturing a compound optical element. The holding devices include a base for supporting a main surface of an edged optical element and either exactly three pegs or a plurality of clamps. The pegs are arranged so that two pegs are in contact with a first area of the side surface of an edged optical element positioned on the base while the remaining peg is in contact with a second area of the side surface only if a specific portion of the first or of the second area is within a specific position and orientation range about three perpendicular axes. The clamps are arranged to collectively hold an edged optical element positioned on the base by restricting its mobility with respect to three degrees of freedom.
