Embodiment Construction

[0040] figure 1 A longitudinal sectional view of a laser processing head 1 designed as a laser cutting head of a laser material processing machine is shown. The laser processing head 1 has an optical element 2 configured as a lens. The optical element is arranged in a lens barrel 3 , wherein the lens barrel 3 is replaceable, in particular removable from the laser processing head 1 . A threaded ring 4 is shown at the upper end of the lens barrel 3 , which holds the lens barrel in the laser processing head 1 . The threaded ring 5 holds the optical element 2 in the lens barrel 3 and thus in the laser processing head 1 through a spacer 6 .

[0041] Arranged on the optical element 2 is a transponder 7 in the form of a radio frequency identification tag (RFID tag). The transponder is opposite the reading and / or writing device 8 . Information from the transponder 7 can be read out by means of the reading and / or writing device 8 and information can also be written into the transpo...

Abstract

The invention relates to an optical element (2) intended for installing in a laser material machining tool and having first surface that is optically unused and/or not captured by the laser beam during operation of the laser machining tool, wherein a transponder (7) is arranged in the region of the surface and comprises readable information with respect to the optical element (2).

Description

technical field [0001] The invention relates to an optical element defined for installation in a laser material processing machine. [0002] Furthermore, the invention relates to a laser processing head with an optical element and a method for operating a laser material processing machine. Background technique [0003] The laser material processing machine has a laser processing head which may comprise at least one lens as an optical element etc. or, in the case of a YAG laser material processing machine, as an optical element in addition to the lens as an optical element and a protective window. In the field of laser material processing, optical components do not have identification marks beyond the laser-engraved material number and production date. However, some particular problems occur in laser material processing in the high power field. In particular, optical components may be contaminated and / or worn or aged. Getting information about these and using that informa...
