This multi-channel, multi-spectral lighting system guarantees the reliable capturing of wafer identifications including OCR, barcodes and 2D-codes regardless of the marking technique (hard-marked, soft-marked, or super-soft-marked). Field proven identificaiton algorithms are geared to the semiconductor industry's requirements. It works with 1700 or 2700 aligners to record ID's on regular, semi-clear and clear wafers.
