Patent number: 7063259Abstract: An optical device which emits a laser light beam (3) comprises a laser light beam emission source (20)(for example, a semiconductor laser diode) including a source of the laser light beam housed in a package (6) provided with a light beam emission window (11). The emission window is shaped so as to be a diaphragm (12) which selects a predetermined portion of the light beam. The size of the window is smaller than the size of the light beam in a transversal cross section taken at the emission window. Moreover, the device comprises a lens (13) for focusing the portion of the light beam. The focusing lens can in turn be housed in the emission window and be itself a diaphragm. In particular, the lens is a Fresnel or diffractive lens.Type: GrantFiled: February 1, 2001Date of Patent: June 20, 2006Assignee: Datalogic S.p.A.Inventor: Guido Maurizio Oliva

Patent number: 7023626Abstract: The invention relates to an optical device for focusing a laser beam, comprising a source of emission of a laser beam, for example a substantially elliptic and astigmatic laser beam, a focusing lens of the laser beam and first aperture adapted to select a central portion of the laser beam. The first aperture is directly applied on the focusing lens, and comprises a coating made of a substantially opaque material which are applied (for example, by spraying, sputtering, evaporation, printing, painting) on a peripheral portion of a front surface of the focusing lens so as to allow the propagation of the central portion of the laser beam and obstruct the propagation of a surrounding portion of beam. The device of the invention is extremely simple from the constructive point of view, and is inexpensive and small-sized.Type: GrantFiled: February 3, 2000Date of Patent: April 4, 2006Assignee: DATALOGIC S.p.A.Inventor: Guido Maurizio Oliva
