Linebeam Optics
For our Linebeam optical systems, we use refractive beam shaping, which treats the multimode laser beams anamorphotically and precisely superimposes the two axes in a common plane. For the short axis, a Gaussian or flattop profile with widths ranging from a minimum of <20 µm to >100 µm is generated at the focus, while the long axis provides a homogenized beam profile with outstanding homogeneity and lengths ranging from <1 mm to >1000 mm.
Line beam technology allows the coupling of multiple lasers to be effectively coupled and large areas to be processed with precision.
Field Beam Optics
Field beam optics shape the multimode laser beams in both axes and generate light fields with high homogeneity with sizes ranging from <0.2x0.2 mm² to > 33x26 mm² and pulse energies of over 15 J. This enables a full-area laser process for machining highly complex components.
Projection Systems
High laser power and precision – two contradictions that we uniquely combine in our projection optics. Multi-lens systems and aspherical components are used to minimize optical errors, also at large image fields. Selected materials and clever designs enable high performance even with laser powers up to the kW range.
Optomechanics
Whether it's a homogenizer array with micrometer-level precision or a cylindrical mirror exceeding 1000 mm in length, the optical components involved demand specialized optomechanics. We design and manufacture these in-house to meet the respective requirements: precise, stable, and accurately adjustable.
Functional Units
Pure power is useless without control. Our optical systems are equipped with high-performance shutters, beam dumps, and variable attenuators that have been developed and continuously improved based on industrial customer requirements. Motorized optical groups are equipped with precise absolute encoders and networked control systems that enable simple and reliable integration. Contactless position sensors and monitoring systems log the operating status and detect wear and tear to prevent system failure.
Beam Shaping
Depending on the laser type (single mode with low M² vs. multimode with high M²), we have developed various technologies for shaping the laser beam. These have been continuously improved and adapted to the respective lasers in order to achieve maximum efficiency and precision. Our experience ranges from IR to DUV, from ps to ms pulse length and from CW to >1000kHz repetition rates. Several different laser sources can be combined depending on the process requirements.
Metrology
Problems can only be solved if they can be measured. Based on this experience, we often develop the metrology for our systems ourselves, as it is often impossible to buy anything that exactly fulfills the purpose. Our developments include high Power Beam profilers, and beam position monitors, pulse length and energy measurement and much more. Many of these are also available online as process control. We see high customer requirements as an opportunity to make our machines even more controllable and reliable.
Optics Simulation
High-performance simulation is essential to the development of our optical systems. Customized programs enable the simulation of individual assemblies up to complete optical systems and occurring effects, as well as a prediction of possible performance and parameters.
Constant feedback of results from the laboratory into the simulation is one of the key parameters for reliably implementing new developments in a short time.
