High precision thickness measurements of thinnest glass and films

The new IMS5400-TH white light interferometer opens up new perspectives in industrial thickness measurement. The controller offers an intelligent evaluation feature and enables the thickness measurement of transparent objects with highest precision.

  • Nanometer-precise thickness measurements even with varying distances and vibrating targets
  • Stable measurement from a large distance, even of antireflection-coated targets
  • Industry optimized sensors with robust metal housing and flexible cables
  • Measuring rate up to 6 kHz for high speed measurements
  • Easy configuration via web interface

Stable thickness measurement with varying measurement distances

The IMS5400-TH white light interferometer is used for highly accurate thickness measurements from a relatively large distance. A decisive advantage here is the distance-independent measurement, where a nanometer-accurate thickness value is achieved even with moving objects. The large thickness measuring range allows the measurement of thin layers, flat glass and films. Since the white light interferometer works with an SLED in the near infrared range, thickness measurement of anti-reflective coated glass is also possible.

Ideal for industrial environments

Robust sensors and a controller in a metal housing make the system ideally suitable for integration into production lines. The controller can be installed in the control cabinet via DIN rail mounting and provides very stable measurement results due to active temperature compensation and passive cooling. These compact sensors are extremely space-saving and have highly flexible fiber optic cables. Cable lengths up to 10 m allow a spatial separation of sensor and controller. The sensor can be aligned easily and quickly using the integrated pilot laser. Commissioning and parameterization are conveniently performed via web interface and do not require any software installation.

Modern interfaces for integration into machines and systems

The controller offers integrated interfaces such as Ethernet, EtherCAT and RS422 as well as additional encoder connections, analog outputs, synchronization inputs and digital I/Os. When you use Micro-Epsilon's interface modules, PROFINET and EthernetIP are available. This allows the interferometer to be integrated into all control systems and production programs.
