LASER WELDING OPTICS LSO
Lens Shifting Optics (LSO) for Laser Welding monitoring system
Lessmüller Lasertechnik, through LSO in combination with the latest sensor technology, OCT (Optical Coherence Tomography) -Laser welding monitoring system, brings a welding optics to the market that follows the weld seam and automatically compensates for positional tolerances.
The laser welding optics LSO offers:
- Precise and fast online correction of the weld position by detecting and tracing the weld joint
- Real-time control of the weld plane (autofocus)
- Possibility to measure the weld penetration depth (keyhole measurement) by OCT
- Measurement and evaluation of the finished weld seam
- Communication via standard fieldbuses (Profinet, Profibus, Ethercat, Devicenet)
The interaction of LSO and OCT in the video
The non-contact LSO system enables high-precision seam tracking as well as real-time process monitoring and quality assurance when welding with solid-state lasers.

Due to the seamless integration of OCT into the welding optics, the user receives a compact overall system as a black box that can correct autonomously and ensures optimum welding quality.
During the active welding process, the system uses optical coherence tomography (OCT) to ensure precise position determination with the accuracy of 0.05 mm. The position of the weld joint is determined approx. every 10 ms and tracked by lateral lens shift.
When the distance from the component to the LSO changes, the optimum focus position is determined and regulated in real time by the axial lens shift.
Quality assurance algorithms proven in the series production process monitor both position control and the welding process as well as the weld seam and report critical weld seams to the higher-level system control.
If required, the LSO (Laser welding monitoring system) can be expanded with Lessmüller’s WELDCHECK system to maximize functionality.
Advantages with LSO
Advantages with OCT
Whether integrated into a processing laser or used as a stand-alone, by using the OCT system from Lessmüller Lasertechnik you are making the choice for the most powerful quality assurance for welding processes on the market. – Laser welding monitoring system.
The possibility of using the system for all types of process monitoring, i.e. as a pre-, in-, or post-process, guarantees you the technically best possible welding quality in your manufacturing production according to today’s standards.
The primary task of OCT sensor technology is to avoid incorrect positioning of the processing optics or the laser beam. This can be done before welding by detecting the actual weld seam geometry and making preventive corrections, if necessary, or during welding by continuous, automated readjustment (seam tracking).
Furthermore, the weld penetration depth can be determined and monitored during welding. If defects occur, the ongoing process can be interrupted and defective parts can be prevented from being processed further.
Finally, the OCT from Lessmüller Lasertechnik can even measure the topography of the weld seam and check it for defects, both during and after the welding process.
Since OCT works independently of extraneous or interfering light, detectability and measurability can already be estimated in the planning phase of impact geometries. There is no need to create complex illumination simulations as for camera systems.
By using OCT for keyhole measurement, it is possible to determine whether the welding process is safe, constant and reliable in the essence during the initial welding tests, even before the feasibility studies. Thus, OCT contributes to the improvement and optimization of welding processes.
For the measurement of the POST process, offline tests can also be made parallel to the still ongoing process development.
All large and well-known OEM manufacturers have been using Lessmüller sensor technology for years. In the field of electromobility, battery manufacturers from China and Korea are among our customers.
Overall, we work with many system integrators: Bergmann & Steffen, Erlas, Felsomat, Thyssen Krupp Engineering, Manz, Comau, Evobeam, Aumann and others.

APPLICATIONS
Here our OCT solutions have already proven themselves
OCT has established itself in practically all manufacturing productions as an optimal and comprehensive tool for quality assurance of industrial laser welding processes. Our laser welding monitoring system.
The technology for laser welding monitoring system is trend-setting and is already considered the standard solution par excellence in many industries.
And the development continues: For example, Lessmüller Lasertechnik is supporting the Friedrich Alexander University (FAU) Nuremberg-Erlangen in the KIKoSA research project to optimize laser welding processes through the use of artificial intelligence (AI).
