Paul Temple Adiabatic Laser Calorimeter Adiabatic Laser Calorimeter A device for measuring energy absorptance of a sample material. A temperature controlled enclosure, in which a sample is suspended, is placed in an evacuated container.
Calibration is accomplished by means of a known power dissipation in the sample.
The sample material is irradiated by an energy beam of known power and a temperature rise is compared to the calibration temperature rise. Means for scanning the sample is also provided.
