Laser / Light Flash Analysis (LFA)

RSS
Laser / light flash analysis (LFA) is a test that determines the thermal diffusivity of a solid, fluid or powder sample.

Laser / light flash analysis (LFA) starts with a quick pulse of energy that rapidly heats one side of the sample. Heat energy is then transmitted through the sample and is detected by an infrared sensor on the other side. Thermal diffusivity of a sample with a known density and thickness is then determined based on the time interval between the pulse being fired and the infrared sensor picking up the energy from that pulse.
