Abstract
Modern day laser flash apparatuses can only measure the thermal conductivity of materials if the thermal conductivity (K) is between 0.1 and 100 W/mK. Our goal was to create a system that could relay reliable data for materials with an expanded thermal conductivity range down to 0.001 W/mK. To accomplish this, a more powerful laser flash was used in conjunction with a circuit designed to amplify the signal so that the thermal conductivity could be deduced.
