Multi-Changer

Layer thickness measurement with 6 quartz oscillators and 12 test glass positions

Optical thin-film coatings are gaining increasing importance in industrial processes and throughout the field of high technology. Depending on the application, very special coatings or coating systems are required that must meet certain criteria regarding:

• Transmission behavior
• Reflection behavior
• Absorption behavior
• Dispersion
• Resistance to high temperatures and humidity
• Abrasion resistance, adhesion

Optical coatings and coating systems with only a few nanometers of layer thickness, as needed for beam splitters, conversion filters, blocking filters, bandpass filters, heat protection filters, as well as for cold light and laser mirrors, must be manufactured with utmost precision.

For this reason – and as part of a complete in-situ measurement system – ONLINK Technologies GmbH has developed the MULTI-CHANGER.
