ZEISS Spectroscopy
modern converting machine for foil
Thin Film Metrology

Perfection from constant layer evaluation ZEISS spectrometer systems for Converting

  • Steady and reliable process control
  • Clear and smooth substrate (e.g. PET)
  • Rough and opaque substrate (e.g. paper)
  • Layer thickness from 50 nm to 100 µm
  • Fast and efficient in high-throughput coating systems

A multitude of methods

Depending on the layer thickness, different algorithms or methods must be used to determine the layer thickness from the spectra, such as Fast Fourier Transformation, chemometric / near-infrared (NIR) analysis, physical modelling or UV measurement.

Tiny tolerances

Contact-free and non-destructive, high accuracy measurement is needed to meet stringent requirements for layer thicknesses, basis weights, color impression and similar optical parameters, as well as to determine the homogeneity on the surface of the end product.

Real time optimization

Relevant parameters must be recorded, displayed and evaluated in real time. This enables prompt intervention by personnel, automated control as well sorting tasks and classification.

Increased efficiency tailored to you

All the benefits you need for a successful operation

  • Developed for your needs

    Get real time data and compare it with historical and pre-set values. ThinProcess® is the ideal tool to make the most of measurement information and can easily adapt to constantly changing requirements. Placement of optical components is possible inside or outside the vacuum chamber.

  • Fully connected

    Data can be provided to the sensor network through OPC UA and into SQL databases, enabling Industry 4.0 solutions. ThinProcess® can also be integrated into MES environments.

  • More convenient

    ThinProcess® is self-calibrating, self-triggering and synchronizable, making it easy to use and integrate into your systems. Furthermore, real-time data also helps you to make quick decisions during the production process and allows you to complete routine jobs more easily even in high-throughput coating systems.
