Product Description
LGS Single Crystal Wafer Dia 2" X 0.5mm One Side Polished
Introduction :
The gallium lanthanum series materials such as La3Ga5SiO14 (LGS) have the characteristics of low surface acoustic wave velocity and large electromechanical coupling coefficient, which are conducive to the miniaturization of the prepared devices. In addition, this type of crystal has a high melting point and is relatively stable at high temperatures, and can be used to prepare high-temperature sensors and filters.
Main Application :
- Electro-optic Q-switch
- SAW device /BAW device
- Sensor
- High and low temperature change laser
