The Variable Angle ATR, is a traditional in-compartment accessory with the ATR crystal mounted vertically with respect to the spectrometer baseplate. Its optical layout allows continuous adjustment of the incident beam angle between 30 to 60 degrees. This accessory is suitable for the analysis of solids, films and coatings, but for obvious reasons, it cannot be used for working with liquids.  VATR is an excellent, low-cost tool for teaching the principles of internal reflection spectroscopy, and for basic research.

  • 30° to 60° variable angle of incidence
  • Economical introduction to ATR techniques
  • Full control over number of reflections and depth of penetration
