Laser absorption calorimeter
Absolute absorption laser calorimeter developed by the Laser Research Center (LZH) in Hannover, Germany, iso standard test system.
- Used to test optical materials, thin film materials, energy absorption measurements of lasers, and scientific research to analyze the properties of materials and thin films.
- Suitable for lasers of different wavelengths such as 193nm, 248nm, 266nm, 532nm, etc., especially for vacuum ultraviolet wavelength test accuracy is high.
- High-performance optical material analysis, ultra-smooth surface processing, vacuum UV optical coating, etc.
System functionality
- Vacuum optical path is charged with N2 protection
- Fully automated test software program control
- EMP protection test sample chamber
- Different lasers are available
- Automatic laser attenuation sheet
- Absolute correction with 100% suction sample by electrical heating
- The system is sensitive to both linear attraction and nonlinear absorption
- Multi-sample chamber option
