ConfocalDT IFC2471HS

ConfocalDT IFC2471HS

Order Catalog


The confocalDT 2471 HS controllers are used for fast distance and thickness measurements of highly reflecting shiny surfaces, enabling measuring rates up to 70kHz without having to use an external light source. The confocalDT HS controllers are considered one of the fastest confocal measurement systems in the world. The controller can be operated with any IFS series sensor and is available as IFC2471LED standard version for distance measurements or as IFC2471MP LED multi-peak version for thickness measurements. Data output is via Ethernet, EtherCAT, RS422 or analog output.
