  • Measure absolute values of thermal diffusivity
  • Anisotropic measurement: In-plane and out of plane directions
  • Dynamic range: Organic films to Diamonds
  • Contact with sample: Contactless measurement
  • Sample shape: Free (disk shape is preferred)
  • Thermal conductivity could be derived from the thermal diffusivity
