Get Started with Laser Flash Analysis (LFA)

For the precise measurement of thermophysical properties such as thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast and precise method. Learn in our new video about the basic workflow of an LFA measurement.

Thermal conductivity and thermal diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material. Common techniques for determining thermal conductivity include the Heat Flow Meter (HFM) and Guarded Hot Plate (GHP). For the precise measurement of thermophysical properties such as thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast and precise method.

In Laser Flash Analysis, a short energy light pulse heats the front surface of a plane-parallel sample. From the resulting temperature increase of the rear face measured with an infrared (IR) detector, the thermal diffusivity and, if a reference specimen is used, specific heat can both be determined.

Not only sample preparation plays an important role for LFA measurements, but also other essential things have to be taken into account. Learn in our new video about the basic workflow of an LFA measurement:

  • Preparing the detector
  • What to consider when preparing the sample and why a graphite coating is necessary
  • The difference between high- and low-temperature systems
  • Which sample holder to choose depending on your sample
  • How to define the temperature program
  • Evaluation methods for your measurement using the PROTEUS® Software
