RA 1nm Lithium Niobate Wafer for Visible to Mid-IR Applications - 3-8" Sizes, 0.18-1.00mm Thickness
RA 1nm Lithium Niobate Wafer is engineered for superior performance across visible, near-infrared, and mid-infrared spectral regions. With exceptional optical properties and high electro-optic coefficients, this wafer is ideal for advanced photonics applications.
Lithium niobate offers transparency between 0.25 and 5.3 μm, making it suitable for visible, near-infrared, and mid-infrared applications. The material exhibits superior piezoelectric effects, nonlinear optical properties, photoelastic effects, and Pockels effects (linear electro-optic effects), with coefficients significantly larger than comparable ferroelectrics.
- Optical amplitude and phase modulators
- Pockels batteries and laser Q-switch modulators
- Optical parametric oscillators and parametric amplifiers
- Second harmonic generators for 1.064 μm Nd:YAG lasers and 1.3, 1.55 μm semiconductor lasers

We specialize in piezo wafers and were the first to work with Single Crystal Quartz in China approximately 30 years ago. Our expertise extends to LiNbO₃, LiTaO₃, Quartz glass, LGS, and CTGS materials. We are particularly recognized as a premier supplier of piezo quartz, exporting millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Yes, we offer complete customization capabilities and can fabricate according to your specific requirements. Our experienced team can provide technical recommendations if you need assistance with material selection. We also maintain standard wafer inventory for immediate availability.
We can ship using your preferred courier service (DHL, FedEx, UPS, etc.) and will optimize packaging to minimize shipping costs. Alternatively, we can handle freight arrangements using our established relationships with international carriers.
We employ specialized packaging techniques to protect fragile wafer products during transit, including vacuum sealing and buffer materials. For complete assurance, please follow our acceptance check procedure to document any transit damage for immediate resolution.
Important: Products are fragile and specially packaged. Handle with care upon receipt and inspect outer carton condition before opening. Document any damage immediately without removing products from packaging and contact us for resolution.
