LFA 457 MicroFlash®


Laser Flash Apparatus


The LFA 457 MicroFlash® is the most up-to-date and versatile LFA system for research and development and for all applications involving characterization of standard and high-performance materials in automobile manufacturing, aeronautics, astronautics and energy technology.


The innovative infrared sensor technology employed in the system enables measurement of the temperature increase on the back surface of the sample, even at temperatures of -125°C.

The instrument can be used for small and large sample sizes of up to 25.4 mm diameter and, with the integrated sample changer, measurements can be run on several samples at the same time.
