MSE PRO LiNbO3 Lithium Niobate Crystals and Wafers
SKU: SU1001
Lithium Niobate (LN) is a ferroelectric material with excellent electro-optic, nonlinear, and piezoelectric properties. Lithium niobate crystals are important materials for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and various other linear and non-linear optical applications. Find lithium niobate crystals and wafers for sale at MSE Supplies.
The largest use of Lithium Niobate (LN) is in SAW devices used in telecommunication devices. When voice communication and data communication are performed, SAW devices such as SAW filters and SAW duplexers are mounted in communication devices as filters for preventing noise and interference. Lithium Niobate (LN) crystals are also used in optical applications.
