The calotte grinder Calotte L

In the production and development of thin coatings with PVD technology (Physical Vapor Deposition), the determination of the coating thickness is one of the most important measurement methods.
The calotte grinder Calotte L:
  • is used to determine coating thicknesses and coating rates
  • uses a broad projection of the layer thickness, which can also be measured with low magnification (Vmin =50)
  • measures layer thicknesses between 0.1 and 30 µm

To grind the layer, a hardened steel ball is rotated on the coated substrate surface. Since many coatings are harder than the steel ball used, diamond suspension is additionally introduced between the coating and the steel ball via a pipette.

With calotte grinding unit, CemeCon offers the possibility of meeting the diverse applications in coating production and evaluation. The "Kalottchen L" calotte grinding device is ideally suited for fast and simple layer thickness determination of PVD layers.
