4" Lithium Tantlate LiTaO3 Wafer Polarized For Optical And SAW

 

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.

 

Crystro's LiTaO3 crystal is grown by Czochralski method.Max diameter reach 4inch,it's now the biggest size in this filed,we can custom size and specs ,rougness<0.5nm.

Other optical single crystals like GGG,SGGG,TGG,TSAG are also available.
 
 

Crystro provides:

  • Excellent photoelectric property
  • High Damage Threshold
  • High Curie Temperature
