The varioSCAN product line is ideal for applications requiring f-theta lenses, as well as applications for which these costly lenses are unavailable. In the second case, the focusing system provides a plane focusing surface in addition to z-adjustment of the focus. Besides the processing of three-dimensional surfaces, classic fields of application requiring z-axis manipulation include additive manufacturing (3D printing) and laser cutting. In many of these applications, there is a trend towards higher laser powers, the use of ultrashort pulse lasers and the demand for improved image quality and positioning accuracy.
