laser flash apparatus for the determination of thermal diffusivity and conductivity

Discovery Laser Flash DLF 1600?s source module is a freestanding unit employing a custom Class 1 35 J Nd:Glass laser pulse source. It provides a collimated, monochromatic energy pulse to specimens heated up to the temperature of 1600?C. The laser radiation is delivered via a proprietary fiber optic delivery wand which ensures a 99% homogenized laser pulse. Leading to much more accurate measurements than any direct firing laser pulse instruments. The laser source produces a 300 ?s to 400 ?s pulse width.

DLF 1600 furnace employs MoSi2 heater, and a high-purity alumina muffle and specimen holder, supporting continuous operation up to six specimens from RT to 1600?C in air or inert gas, or in vacuum to 10-3torr. Coaxially symmetrical heat zone, specimen carousel?s design, and thermocouple located at its center ensure an extremely uniform specimen temperature uniformity. The baffle structure prevents turbulence interference on the thermogram signal and assure accurate measurements especially up to 1600?C. The module includes an LN2-cooled IR detector. Simple to operate and safe to use, the system is suitable for research and development programs, as well as quality control.
