MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617062127 A) filed by Trumpf Laser Se on May 15, 2026, for Device And Method For Machining A Workpiece.
Inventors include Kleiner, Jonas; Flamm, Daniel; and Mayer, Jonas.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a device and a method for machining a workpiece (4), in particular for impressing an anti-glare functionalisation, by means of laser pulses (100) of a laser (1), comprising a laser (1), in particular a short-pulse laser or an ultra-short-pulse laser, which is configured to provide a laser beam (10) with laser pulses (100); a first diffusing lens (2) and a second diffusing lens (2'), which are each configured to scatter the laser beam (10) and to impress a locally randomised intensity distribution onto the laser beam (10) in the focal plane (12), wherein the first diffusing lens (2) and the second diffusing lens (2') successively scatter the laser beam (10); at least one optical focusing system (3), which is configured to focus the laser beam (10) onto a focus zone (120) in the focal plane (12) on the workpiece (4), wherein the laser beam (10) is applied to the workpiece (4) and as a result the workpiece is machined; an advancing device (5), which is configured to move, with an advancement (V), the laser beam (10) and the workpiece (4) relative to one another, wherein the advancing device comprises a scanner device (50) having a first scanner element (500) and a second scanner element (502), wherein a movement of the scanner elements (500, 502) produces an advancement, wherein the second scanner element (502) comprises the second diffusing lens (2'), wherein the movement of the scanner elements modifies the locally randomised intensity distribution.
