Laser light and the automotive industry are closely tight together. On the one hand, laser applications such as welding, cutting, brazing, marking or cleaning play a key role in the automotive industry. Understanding and ensuring the quality of the laser beam is the first step towards high product quality and sustainable processes. On the other hand, relatively lower-powered LiDAR products are gaining more and more importance.
Understanding how the laser light is behaving when projected into a space is crucial to the product's accuracy and long-term success. Ensuring the laser beam quality is essential in both kinds of applications.
When using multi-kilowatt lasers in the production environment, even slight deviations in the location of the focal point or minor variance of laser power exert a massive effect on the entire processes. Because of this, measuring the laser parameters is not only important when a laser system is developed or produced, it is equally as important once the system is deployed for production.
Ideally, the laser beam is monitored continuously during the manufacturing processes. And even if the production of bad parts gets traced back to a laser-based manufacturing machine, it is essential to know what happened with the beam.
Due to the tremendous progress in autonomous driving there are new and different laser applications gaining importance: High power VCSELs are used in LiDAR systems, low power VCSELs for proximity sensors or face and gesture recognition.
Finding the right laser measurement device is the first step to ensure quality and sustainability of the process and the safety of the users.
