Achieving high-precision and reproducible results is a challenge when producing electronics with ultrashort laser pulses. With the new F-theta lens for 532 nanometers, Jenoptik is releasing another lens for the high-volume laser production of Printed Circuit Boards (PCBs).
The new F-theta lens for 532-nanometer applications is the second high-power lens for use in the green wavelength range in Jenoptik’s SilverlineTM lens portfolio. The solid fused silica lens is especially designed for high-volume electronic production with ultrashort pulse lasers such as PCB depaneling.
Enabled by its low-absorption fused silica and the high-quality coating, this lens withstands ultrashort pulse lasers and lasers with power outputs up to the kilowatt range. With a focal length of 163 millimeters and a minimum spot size of 13 micrometers, workpieces can be processed in a scan field of up to 65 x 65 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.
