Advantages when measuring refractive index for both thin films and bulk materials: 

  • Unparalleled index accuracy: ±.0002 to ±.0005 (depends on application) 
  • Index resolution:  ±.0001 to ±.0003 (depends on application)
  • Wide refractive index range (1.0-3.35)
  • Wavelengths ranging from 405-1550 nm
  • No advance knowledge or modeling of samples required    
  • Little/no sample preparation required, no coupling fluids 
  • Easy to use with flexible samples
  • Also measures liquids
