Wafer-form defined lighting guarantees optimum illumination of the edge. Telecentric measurement systems allow for high precision with regard to the edge-break control (up to 60 µm x 60 µm) and combined measurement tasks. Due to their special imaging concept they can stand up to displacement and changes in height.
