In modern industry, laser projection systems are used to project lines, dots or entire contours onto surfaces or materials. With this innovation, unwieldy stencils that are difficult to produce become superfluous and time-consuming calibration is a thing of the past. Within seconds, exact positioning of components on the material surface can be visualized, contours can be displayed, or position checks of the components can be carried out. Laser projection makes production processes faster, more flexible and more ergonomic for workers and workers. Due to the automatic alignment of the laser projection system, even more difficult areas can be reached quickly and precisely, and shapes can be projected without any problems, e.g. when projecting marking points in car body construction.
