For advanced applications in telecommunications, frequency control, and optoelectronics, our LiTaO₃ (Lithium Tantalate) Wafers offer unparalleled piezoelectric and electro-optic properties. Engineered for precision and reliability, these wafers are ideal for surface acoustic wave (SAW) devices, optical modulators, and high-frequency filters, where superior stability and low insertion loss are critical.
Crafted from single-crystal LiTaO₃, our wafers feature excellent temperature stability, high electromechanical coupling coefficients, and exceptional optical transparency (0.4–5 μm wavelength range). Their low dielectric loss and high Q-factor ensure minimal signal degradation, making them perfect for 5G infrastructure, RF communication systems, and laser technologies.
Available in custom orientations (e.g., X-cut, Y-cut, Z-cut), diameters, and thicknesses, our LiTaO₃ wafers are meticulously polished to meet stringent surface roughness and flatness specifications. Whether for research, prototyping, or high-volume production, our wafers deliver consistent, high-performance results.
Elevate your technology with the industry’s leading LiTaO₃ solution—choose our wafers for unmatched precision and reliability. Contact us today to discuss your requirements and secure a competitive edge!
