Lithium tantalate (LiTaO3) is a perovskite which possesses unique optical, piezoelectric and pyroelectric properties which make it valuable for nonlinear optics, passive infrared sensors such as motion detectors, terahertz generation and detection, surface acoustic wave applications, cell phones and possibly pyroelectric nuclear fusion.
Nova have years of experience of supplying high precision LiTaO3 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.
