VO2 Phase Change Characteristic Test System STA-VOP
Vanadium dioxide ( VO2) is a kind of metal oxide with phase transition property. Its phase transition temperature is 68℃, which can induce reversible metal-insulator phase transition of VO2. With the phase transition, the crystal structure, resistance, infrared light transmittance, refractive index and magnetic susceptibility of VO2 change dramatically. It is precisely because of the phase transition temperature near room temperature and the sudden change of physical and chemical properties before and after phase transition that VO2 has a very wide application prospect in the fields of intelligent temperature control film, optical device, electronic device and optoelectronic device, military protection device, etc.
Features
- Integrated system design and simple operation
- Dual optical path design, real-time monitoring of laser power
- The test sample holder can be customized according to the test sample
- Real time measurement of laser power through VO2 samples
- The measurement results are intuitive and storable for subsequent processing and analysis
VO2 Phase Change Characteristic Test System
Experiment Example
The VO2 sample is heated by laser irradiation, and the laser power through VO2 sample is monitored in real time, and then the real-time transmittance and other parameters of VO2 sample are obtained, which can be used to study the phase transition characteristics of VO2.
