Laser flash analysis

Laser Flash Analysis (LFA) is a tool scientists use to measure how quickly materials conduct heat energy. It works by shooting a short burst of laser light at a sample, like a piece of metal or a plastic. The laser light heats the material up very quickly, and the heat energy is then released back out into the air in the form of infrared (a type of light). Scientists measure how quickly the infrared light is released, and this tells them how quickly the material is conducting heat energy. This helps them figure out how good a material is at conducting energy, and they can use this information to develop better materials.
