Dia 2inch Thick 0.5mm Langasite Single Crystal LGS Substrate

Lanthanum gallium silicate ( La₂Ga₅SiO₁₄ ) is a phenomenal invention. Though langasite was initially developed as a laser crystal, it revealed a remarkable combination of piezoelectric qualities, which opened up new opportunities to use the LGS crystal in radio frequency devices. The main applications of langasite crystals now is SAW filters and SAW resonators. Experts agree that LGS is the best choice for high-efficiency broad band frequency devices because it possesses exceptional frequency-temperature characteristics, a very high index of electromechanical coupling and unparalleled Q-factor.

Crystro's LGS crystal has High thermal stability,low equivalent series resistance ratio and electro-mechanical coupling coefficient is 3-4 times than quartz.

Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.
