  • Patent number: 8144739
    Abstract: The bandwidth selection mechanism includes a first actuator mounted on a second face of a dispersive optical element, the second face being opposite from a reflective face, the first actuator having a first end coupled to a first end block and a second end coupled to a second end block, the first actuator being operative to apply equal and opposite forces to the first end block and the second end block to bend the body of the dispersive optical element along the longitudinal axis of the body and in a first direction normal to the reflective face of the dispersive optical element. The bandwidth selection mechanism also includes a second actuator being operative to apply equal and opposite forces to bend the body along the longitudinal axis of the body, in a second direction perpendicular to the reflective face of the dispersive optical element.

  • Publication number: 20100149647
    Abstract: A mechanism for bandwidth selection includes a dispersive optical element having a body including a reflective face of dispersion including an area of incidence extending in a longitudinal axis direction along the reflective face of the dispersive optical element. The body also includes a first end block, disposed at a first longitudinal end of the body and a second end block, disposed at a second longitudinal end of the body, the second longitudinal end being opposite the first longitudinal end.

  • Patent number: 7659529
    Abstract: A method and apparatus is disclosed that may comprise an ultraviolet light source; an optical element within an optical path of the light source mounted on an optical element mount; a vibration damping mechanism operatively connected to the optical element or to the mount which may comprise a wire mesh pad. The optical element may comprise a center wavelength selection optical element, which may comprise a grating, a mirror, or a prism. The vibration damping mechanism may comprise the wire mesh pad comprising an elastic interface between a driving mechanism lever arm operable to move the optical element or the mount and a driving lever arm actuator. The vibration damping mechanism may comprise a mass damping mechanism comprising a mounting plate connected to the optical element or to the mount; a damping mass; the wire mesh pad comprising an elastic interface between the mounting plate and the damping mass.
