Lithium Tantalate (LiTaO3), referred to as LT, is a crystal with a perovskite structure. LiTaO3 exhibits distinguished optical, piezoelectric, and pyroelectric properties. For different applications, the critical parameters of LITaO3 differ. Optical grade LiTaO3 crystal wafers boast a unique set of properties that make them ideal for optical applications. Optical grade LiTaO3 exhibits high optical transmission across a broad spectrum, spanning from ultraviolet to near-infrared wavelengths. The strong electro-optic effect of LiTaO3 allows for efficient modulation of light with low drive voltages, enabling the manipulation and modulation of optical signals for data communication and signal processing. In addition, LT possesses consistent optical characteristics throughout its volume and low optical absorption, facilitating efficient light transmission with minimum distortions, aberrations, or other undesirable effects.

Hangzhou Shalom EO offers optical grade lithium tantalate (LiTaO3) crystal ingots, blanks, wafers, and substrates, both off-the-shelf and custom products are available. Advanced facilities are equipped for crystal growing, wafer cutting, lapping, and polishing. Before shipping, a stringent testing process is taken under our ISO9001-certified QC system.
