The combination of f-theta lens and deflection unit is an ideal solution for many marking and engraving applications. After all, for small and medium-sized working fields, it offers small focus diameters and good flat field correction with low spot variations. 

However, the workpieces are not always flat. Especially when cleaning components from paint, oxide layers or oil, cutting flexible printed circuit boards or marking, it is important to follow the contour of the component in order to achieve the desired processing result. It is also important to correct the focus position during the process when deep engraving or drilling and cutting glass. 

For these applications, the FOCUSSHIFTER RD-14 is the right choice. It adds an adjustable lens system to the combination of f-theta lens and deflection unit, allowing the z-position of the focus to be set dynamically. As a result, layer-by-layer processing (2.5D) as well as processing in space (3D) are both possible. Thanks to its extremely compact design and versatile mounting options, it can be flexibly integrated into laser systems.

The FOCUSSHIFTER RD-14 therefore offers system integrators an attractive solution for extending laser systems to three-dimensional workpieces. And thanks to the f-theta lens, the FOCUSSHIFTER RD-14 performs particularly well when processing workpieces with different height levels.
