Lithium Niobate Wafers Maximize

Lithium Niobate Wafers

Lithium niobate wafers is typical crystal material used in surface acoustic wave filters, interdigital transducers, optical modulators, pyroelectric IR detectors, etc.

More details

Lithium tantalate (LiTaO3) and lithium niobate (LiNbO3) are two kinds of typical multifunction crystal materials, and are widely used in surface acoustic wave filters, interdigital transducers, optical modulators, electro-optical switches, pyroelectric IR detectors, etc.
