Abstract: An optical arrangement for a laser beam includes an f-theta lens. The f-theta lens is disposed in a divergent beam path of the optical arrangement in order to focus the laser beam into a focus plane. The focus plane is located at a distance from a focal plane of the f-theta lens.

Abstract: A processing head for guiding a laser beam for processing a workpiece includes a housing main body configured to accommodate a beam guiding element. The housing main body has a first main surface section and a second main surface section. The processing head further includes a functional module configured to connect to the housing main body or to be inserted into the housing main body. The first main surface section and the second main surface section of the housing main body are aligned with one another, at least partly surround a free internal volume of the housing main body, and are configured differently from one another for receiving and/or for inserting the functional module and/or a functional component.

Abstract: A scanner device configured for 2-dimensional deflection of a laser beam by mirrors that are each pivotably supported about an axis and that are driven in a motorized manner, includes a first motor-mirror unit that has a first mirror and a drive motor, and a carrier for securing the first motor-mirror unit. The first motor-mirror unit is selected from one of two different possible motor-mirror units, each of which has an assembly flange, an identical abutment face, and can be selectively releasably secured with the abutment faces to the same first assembly face of the carrier. The two different possible motor-mirror units differ from each other with respect to the mirror size and/or mirror position in the carrier.

Abstract: An F/theta lens system for focusing high-power laser radiation in a flat image field including at least two lenses. The at least two lenses are arranged sequentially in a beam path, where the at least two lenses are made from a material that is stable when exposed to laser radiation having a power of more than 1 kW, and at least one of the lenses has at least one aspherical lens surface.

Abstract: A device for focusing a laser beam includes a first telescopic configuration and a second telescopic configuration. The first telescopic configuration includes a collimating optical element for collimating the laser beam and a downstream focusing optical element for focusing the laser beam onto a focal point. The second telescopic configuration includes a first lens and a downstream second lens disposed in the divergent beam path upstream of the first telescopic configuration. The first and second lenses of the second telescopic configuration are moveable relative to each other in the beam direction.
