Pyroelectric Lithium Tantalate Single Crystal Material LiTaO3 Crsytal

 

Application: Lithium tantalate (LT) is used as SAW device which screens electromagnetic waves and only picks up specific frequencies. SAW device is used in mobile communication devices, including auto mobiles and TV and VTR tuners.

 

Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo-electric transducers and piezoelectric sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz. These orientations show an optimized bandwidth / insertion loss trade off in performance and are dominating the ever expanding mobile handset sales.

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