Lithium Tantalate Wafers Description 

Lithium Tantalate (LiTaO3), also known as LN crystal, is a kind of typical multifunction crystal material. Lithium tantalate wafer has both chemical and mechanical stability as well as a high optical damage threshold. These properties make LiTaO3 Wafers useful for SAW (surface acoustic wave) devices and optical uses.
