  • Publication number: 20050146783
    Abstract: An optical beam delivery configuration includes zoom lens means (30) and beam scanning means (44) defining an optical path (20) for a light beam. The beam scanning means is disposed after the zoom lens means in the direction of beam delivery. The zoom lens means (30) is arranged to receive a collimated incident light beam (23) on the optical path, and to be adjustable to determine the fluence of the beam when it is incident on the beam scanning means, while maintaining its collimation on exit from the zoom lens means. The beam scanning means (44) is arranged to laterally scan the beam at a downstream treatment location (50) while maintaining the beam's collimation and orientation at the location.
