Laser Calorimetry Weak Absorption Measurement Instrument
LZH calorimetric weak absorption measuring instrument is an instrument for absolute measurement of thermal absorption, developed by the Hannover Laser Center in Germany, and is a thermocouple absorption measuring instrument. The sample is irradiated with a pump laser, and the temperature of the heated area is measured using a high-precision thermocouple, thereby obtaining the absolute absorption information of the sample to the laser of the wavelength.
