Optical-grade lithium niobate (LiNbO3) wafers in 2-, 3- and 4-inch sizes for electro-optic modulators, nonlinear optics, waveguides and SAW devices. X-cut, Y-cut, Z-cut and custom orientations can be reviewed with single- or double-side polishing, and MgO-doped material can be discussed. Send diameter, thickness, orientation, polishing, quantity and any TTV, bow or warp requirements; specifications are confirmed for each quotation.
