Holometrix Laser Flash Apparatus


A laser is used to fire a short pulse at the surface of a thin disk specimen. The heat transfered through the specimen results in a temperature rise on the other surface that is measured by an infra-red detector. Analysis of this temperature change allows determination of thermal diffusivity.
