Industrial Laser Projection

Visualization in seconds by laser

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.

Projection thanks to AR

Projection-oriented Augmented Reality (AR) is a promising working tool. This is an extended reality that also works with laser projection systems. The idea: The projection-based AR environment combines reality with the visual representation of computer-generated additional information. This means that information about the projection is superimposed with reality to form an image. In the future, this will find more and more application in modern industry and will be made possible by powerful projectors and a sophisticated software system. In future assembly processes, for example, components and individual work steps could be projected onto the workstation. The plan: Mark individual components that are necessary for the next assembly step in color or virtually (2D). A 3D model could then be displayed at the workstation to show the employee where the component is to be mounted.

Areas of application of laser projection

Already today, various industries are profiting from the ever-increasing possibilities of projection. 2D laser projection is therefore increasingly used in industry, e.g. in the stone industry. To saw a granite slab, the contour to be sawn is projected onto the granite. If the projection position needs to be corrected, the heavy stone slab does not have to be moved. Instead, a sophisticated software program makes it possible to transfer the displacement of the laser projection to the saw, thus guaranteeing accurate and fast work. 2D laser projectors are also a popular tool in other areas, such as industrial woodworking. Laser projections can be used as positioning aids, e.g. to assist with stop positions or for the exact determination of rows of screws and nails. Laser projection is not only used in manufacturing, but also in areas such as art (aesthetic projection to complement art objects), military (projection for flight simulation) or navigation (projected information on head-up displays in aircraft and vehicles).

Lenses and mirrors for best imaging results

Laser projection is based, besides a complex software unit, on high-quality optical elements. These include special lenses or lens systems or special mirrors for focusing, beam expansion or deflection. Perfect images can be achieved with aspheres, for example, which are free of spherical aberration and guarantee the best imaging results. Beam expansion optical systems are used to generate a desired (laser) beam diameter or to optimize beam guidance over longer optical paths. Laser projection systems also include special mirror systems and prisms, which are used for beam deflection and can be provided with various coatings, e.g. to ensure best reflections.

These and other optical components from asphericon can be used to optimize your laser projection systems.
