Custom F-Theta lens for battery production
Due to the growth of e-mobility, the demand for reliable beam-shaping optics for battery production increases continuously. In cooperation with technology leaders, Jenoptik has implemented these specific requirements in a new F-theta lens for 1064-nanometer applications. High-volume manufacturers can now make use of a custom F-theta lens for battery foil cutting with high-power lasers.
The new F-theta lens is specially designed for the application of laser foil cutting for batteries with 1064-nanometer lasers and is suitable for high-volume serial production with ultrashort-pulse lasers. When developing this solution, Jenoptik took into account the requirements of this cost-optimized market which led to a compact and competitive lens. The lens joins Jenoptik’s SilverlineTM lens family for laser applications in the automotive supply market.
Thanks to the use of low-absorption fused silica and a robust optical coating, the F-theta lens is suitable for applications with ultrashort-pulse lasers and outputs into the kilowatt range. With a focal length of 160 millimeters and a minimum spot size of around 23 micrometers, workpieces can be processed in a scan field of up to 50 x 50 millimeters. The optimized lens design and an innovative lens mounting allow the full performance of the lens to be exploited while not having any back reflections in the lens.
SilverlineTM lenses are used across many sectors for applications such as ablating, drilling, welding or soldering of high-precision structures in plastics and metallic compounds. They convince with high damage threshold and guarantee high-precision and reproducible working results.
