with 6 crystal oscillators and 12 test glass positions

Features and description

Optical thin-film coatings are becoming increasingly important in industrial processes,
as well as throughout the field of high technology. Depending on the application, very
special coatings or coating systems are required which must fulfill certain criteria with
regard to:

  • Transmittance
  • Reflectance
  • Absorption
  • Dispersion
  • Resistive to high temperature and moisture
  • Abrasion resistance, adhesion

Optical coatings and coating systems of just a few nanometers thickness that are
required for beam splitters, conversion filters, cut-off filters, band-pass filters and heat
protection filters, and for cold-light and laser mirrors, have to be produced extremely

For this reason and as a component of a complete insitu measuring system HS-Group GmbH has developed the MULTI CHANGER.

Major features of the MULTI CHANGER:

  • Stable cooling
  • Simple maintenance
  • Integrated 4-fold quartz crystal changer
  • Integrated 12-fold test slide changer
  • Easy control
