The Light/Laser Flash Analysis (LFA) involves applying a short laser or xenon flash pulse to the front surface of a thin, flat sample of known thickness. The resulting temperature rise on the rear surface is measured using an infrared detector as a function of time. The transient temperature response is analyzed to determine thermal diffusivity. Thermal conductivity is then calculated using the material’s density and specific heat capacity. Measurement Range 0.1 to 2000 W/mK Sample size 12.5 x 12.5 mm Min. thickness of 1 mm Temperature range 25 to 1550 °C Material types Solids ASTM/ISO/EN Standards ASTM E1461
