Lithium niobate (LiNbO3) is a synthetic salt consisting of niobium, lithium, and oxygen. Its single crystals are an important material for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and various other linear and non-linear optical applications.
Nova have years of experience of supplying high precision LiNbO3 wafer. Besides standard 2 inch, 3 inch, 4 inch, customized sapphire wafer is also available for us. For other dimension, please feel free contact our sales engineer and we will be glad to discuss the availability of dimension options.
