The "CHRocodile 2 DPS color aberration confocal sensor" is equipped with two independent measurement channels.
In grinding operations, it is necessary to adjust the thickness of the wafer during processing. If using a non-contact, non-destructive optical measurement method, the thickness of the wafer can be monitored during processing without applying stress to the workpiece or damaging it, making it a suitable solution. Our "CHRocodile 2 DPS Chromatic Aberration Confocal Sensor" is equipped with two independent measurement channels. The sensor processes two chromatic aberration probes and synchronizes measurements and outputs in real-time, providing the final height and thickness of the wafer. 【Features】 ■ Development of chromatic aberration probes for harsh environments based on over 10 years of know-how in CMP and grinding interference measurement. ■ Non-contact measurement of wafer thickness in harsh environments. ■ Data acquisition rate of 10 kHz per probe. *For more details, please refer to the PDF document or feel free to contact us.
