Product Description
Doped Lithium Niobate Wafers for Optical Applications
BonTek provides high-quality Lithium Niobate (LiNbO3) wafers doped with 0.25mol% Er or 5mol% MgO for advanced optical applications. These crystals offer exceptional physical, chemical, and mechanical stability with high temperature resistance and corrosion resistance properties.
Key Material Properties
LiNbO3 crystals feature a high Curie temperature (Tc) with no phase transitions from room temperature to Curie temperature, ensuring stable performance and resistance to depolarization. Doping with various ions enables specialized applications including optical waveguide amplifiers, frequency doubling converters, and optical storage media.
Available Doping Options
We offer customized doping with Er:LN, MgO:LN, and Fe:LN formulations. Black reduced LN wafers are available in 3-inch, 4-inch, and 6-inch diameters for all cut angles, with 128°Y and Z-cut options up to 8-inch diameter.

Frequently Asked Questions
What are the products you mainly work on?
We are piezo wafer specialists with over 30 years of experience. We were the first to work with Single Crystal Quartz in China and have expanded to LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization and can fabricate according to your specifications. Our experienced team can provide technical recommendations if you're unsure about specifications. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
We can ship using your preferred courier (DHL, FedEx, UPS) with your account. We optimize packaging to minimize shipping costs while ensuring product safety. We also offer freight services with discounted international courier rates.
