Patent number: 8023165Abstract: Shown is a lens device 16 comprising a displaceable lens 18 and a guide 42, by means of which the lens is guided so as to be capable of being displaced. The lens device 16 comprises a first and a second galvanometric motor 46a, 46b and a first and a second force transmission device 54a, 56a; 54b, 56b, which is coupled to the rotor of the first and second galvanometric motor 46a, 46b, respectively, and which is coupled to the lens 18 at a first and second junction 58a, 58b, respectively. The force transmission device is suitable to convert a rotary motion of the rotor of the first and second galvanometric motor 46a, 46b, respectively, into a displacement motion of the lens 18. The first and the second junction 58a, 58b are thereby spaced apart from one another in a direction at right angles to the displacement direction of the lens 18.Type: GrantFiled: October 31, 2008Date of Patent: September 20, 2011Assignee: Raylase AGInventor: Erwin Wagner

Patent number: 7531772Abstract: 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.Type: GrantFiled: September 30, 2005Date of Patent: May 12, 2009Assignee: Raylase AGInventors: Peter S. Dullin, Alistair Baillie Gill, John Spang

Publication number: 20080180775Abstract: Disclosed is a Galvanometric motor with a rotor and a position detection device, which comprises the following: a deflection element, which is rigidly connected to the rotor and which has a reflection surface, first illumination means in order to direct a first light beam on to the reflection surface of the deflection element, and a first detection device for receiving the first light beam reflected by the reflection surface. The reflection surface of the deflection element is at an angle to the axis of rotation of the rotor, and the axis of rotation of the rotor extends through it. In addition the first light beam is directed on to the reflection surface in such a way that it forms an angle of less than 35°, preferably less than 10°, with the axis of rotation of the rotor.Type: ApplicationFiled: January 17, 2008Publication date: July 31, 2008Applicant: Raylase AGInventor: Alistair Baillie Gill

Patent number: 6834062Abstract: The present invention provides a method and apparatus for controlling laser power, using at least two Brewster windows which are aligned along an axis which is parallel to the direction of the laser beam and which are rotatable around said axis, wherein the first Brewster window is rotated in one direction and the second Brewster window is rotated in the opposite direction. Preferably, both Brewster windows only have to rotate each through +/−45° to control transmission of the laser beam from maximum to minimum.Type: GrantFiled: July 22, 2002Date of Patent: December 21, 2004Assignee: Raylase AGInventors: Stephen Hastings, Peter Dullin, Alistair Gill, Erwin Wagner, Peter von Jan, Wolfgang Hauck

Patent number: 6763045Abstract: An apparatus for laser beam targeting and method of laser cutting or marking of an article is disclosed. In one aspect of the invention, the laser beam targeting apparatus comprises at least one laser scan head comprising at least one motor driven deflector for scanning a linearly polarized laser beam across a target, and a polarization control device comprising at least one Brewster plate wherein the polarization control device rotates the Brewster window around an axis parallel to the laser beam to thereby gradually transmit or deflect the laser beam in order to control the level of laser beam energy scanning across the target in accordance with the movement of the at least one deflector and a laser scanner.Type: GrantFiled: July 10, 2002Date of Patent: July 13, 2004Assignee: Raylase AGInventor: Stephen Alan Hastings
