The Thickness Gauge is a device for relative measurement:
Thickness (µm)
Weight by area(g/m2)
Using Low-energy soft X-Rays, based on a change to X-Rays transmitted.
The System is available for both In-Line and Off-Line.
Examples
Total thickness measurement of Film or Metal Foil.
Thickness measurement of only Coated films.
In the “In-Line” measurement model, the system measures thickness in real-time so that an uneven thickness either widthwise or lengthwise can be corrected immediately.
In the “Off-Line” model, the system measures thickness in the same way as “In-Line”. Furthermore, it is possible to measure only the desired area. The system is suitable for sample inspection and R&D applications.
