The analysis and optimization of combustion processes requires accurate measurement of several parameters, temperature distribution being one of the most important.

Designed for clean combustion environments with high temperature gradient, our Rayleigh Thermometry system provides all the tools needed for measurements of two-dimensional temperature maps in combustion and heat transfer studies. The technique offers very wide dynamic range that can measure variation from room temperature all the way up to flame temperatures within a single measurement.
