Product Details

Pyroelectric Free Black LiNbO3 Wafer 128Y-Cut SAW Grade

The reduction technique is used to produce black lithium niobate (LiNbO3). Black LiNbO3 wafer has a high ability to neutralize charges even if the electric potential occurs instantaneously. The pyroelectric effect of LN wafer is almost eliminated and the transmittance is significantly reduced. The piezoelectric properties of black lithium niobate wafers are no different from those of standard wafers. Therefore, black reduced lithium niobate wafers are widely used to produce higher frequency surface acoustic wave devices.

BonTek is proud to announce that we can offer 3 ", 4 ", and 6 "black LN wafers for all cutting angles.
