Y128-Cut 4 inch 0.5mm LiNbO3 Wafer DSP pack in Cassette
Lithium Niobate (LiNbO3, LNO), an uniaxial ferroelectric with a very high Curie temperature (1500 K). Among other attractive features, one should note its relatively low price, high chemical, thermal, and mechanical stability, availability of big crystals of sufficiently high quality and, last but not least, its lead-free composition.
LNO and the related material LiTaO3 are widely used in surface and bulk acoustic wave devices, optical modulators and waveguides, filters, transducers, acoustic microscopes, etc.
