Product Description
Lithium Tantalate (LiTaO3) Nonlinear Optical Grade Crystals
Lithium Tantalate (LiTaO3) crystals offer exceptional electro-optical and acousto-optical properties, making them ideal for surface acoustic wave devices, bulk acoustic wave devices, piezoelectric transducers, and sensors. The 36° and 42° crystal cuts are particularly optimized for telecommunications applications in mobile phone handsets operating at frequencies from 800 to 2100 MHz.
Key Manufacturing Advantages
- Czochralski growth method with >99.99% purity
- Maximum diameter of 4 inches - industry-leading size
- Surface roughness <0.5nm for precision applications
- Custom sizes and specifications available
