The adapter for the L50 focus lens serves as a spacer between the optics and the focus lens unit of our laser welding systems. It makes it possible to reach even hard-to-reach welding points on components by extending the distance between the optics and the focus lens by up to 150 mm. This adapter is particularly useful when welding into molds is carried out internally or when there are interfering contours. Up to three adapters can be screwed together to bridge the required distance and ensure optimal welding results in complicated areas.
