The confocalDT 2471 HS controllers are used for fast distance and thickness measurements of highly reflecting surfaces. The controllers are equipped with enhanced optical components 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 active exposure regulation feature in the CCD array enables accurate, fast surface compensation on difficult changing surfaces during dynamic measurement processes.

Features N/A
  • Fastest controller worldwide: Measuring rate up to 70kHz
  • Interfaces: Ethernet / EtherCAT / RS422 / Analogue
  • Fast surface compensation
  • Configuration via web interface
  • Sub micrometer resolution
  • Multilayer thickness measurement
  • Robust design with passive cooling
Additional Information N/A The controller can be operated with any IFS sensor and is available as a standard version for distance measurements or as a multi-peak version for thickness measurements.

Due to a user-friendly web interface, the entire configuration process is carried out without using any additional software. Data output is via Ethernet, EtherCAT, RS422 or analogue output.
