Full Automatic Laser Chip Optical Inspection
Description Opto System Laser Diode Chip Visual Inspection Tool VVS2000
The full automatic optical inspection VVS2000 is able to inspect not only potential defects on the top side, but thanks to a dedicated optical stage, also the facets of laser diodes. The geometry of the lasers is irrelevant, because the specialty of this tool is that the diodes do not need to be picked up from the tape. The optical set-up that looks at the facets from the side at an angle and a clever algorithm are able to identify potential defects of 3µm size or larger on the facets while defects of 1µm or larger are detected on the top side. The optics in the VVS2000 make the handling of the chips unnecessary, which saves precious time and increases the throughput. The pictures are analyzed with a state-of-the art algorithm and the pictures can be saved in a database.
