The invention relates to a beam forming lens system for machining material using a laser beam, comprising a two-dimensional axicon array () featuring a plurality of microaxicons () for creating an annular laser beam intensity profile, the microaxicons () being provided with curved lateral surfaces (). The invention also relates to an apparatus for machining material using a laser beam, comprising a beam forming lens system of said type and a focusing lens system () for focusing the laser beam onto a workpiece (). The beam forming lens system is designed to create the annular laser beam intensity profile in a focal plane (F) of the focusing lens system ().

Beam forming lens system for laser cutting, and apparatus comprising same

An add-on module for intercoupling or interposing between a control device, in particular a system control, and a laser machining head of a laser machining system is provided. The add-on module includes: a first interface, and is connectable with the laser machining head and/or with at least one sensor device of the laser machining system via the first interface so as to exchange data; a second interface, wherein the add-on module is connectable to the control device via the second interface so as to exchange data; and a processing unit configured to process data and output the processed data via at least one of the first, second, and third interfaces. Furthermore, a laser machining device includes such an add-on module is provided.

Add-on module for interposing between a control device and a laser machining head of a laser machining system

The invention pertains to measuring, adjusting and/or controlling a distance between a machining head, particularly a laser machining head, and a workpiece, comprising a measurement light source, a beam splitter that splits the light of the measurement light source into a measurement light beam and a reference light beam, a reference arm, through which the reference light beam is guided, an optical system for coupling the measurement light beam into a processing beam path featuring a focusing lens, an optical device for superimposing the measurement light beam, and a measurement and evaluation unit.

Method and device for measuring and controlling a distance between a machining head and a workpiece

A laser processing head includes a housing including a mounting surface for mounting the laser processing head on a carrier; a plurality of optical components arranged within the housing; and an access opening formed in the housing for removing or inserting at least one first optical component among the optical components, the access opening being formed in the mounting surface.

Laser processing head and laser processing system including the same

A device for machining material by means of laser radiation, including a focusing optics for focusing a laser beam onto a workpiece and an adjusting optics for adjusting the intensity distribution comprising at least two plate-shaped optical elements which are arranged one behind the other in the beam path of the laser beam, which are rotatable relative to one another in the circumferential direction, and which each have a surface with a circular pattern of sector-shaped facets which, in the circumferential direction, are alternately inclined with respect to the respective plate plane.
