  • Apparatus for translational displacement of a lens in a laser focussing optical system
    Patent number: 7531772
    Abstract: An apparatus is described for automatically shifting a lens of a laser focussing optical system, the lens undergoing translational motion along an optical axis, being moved by at least one motor which carries out rotational movement. This rotational movement is converted by a linkage into translational movement to shift the lens.
