Product Description
Product Overview
Fe doped Lithium Tantalate (Fe:LiTaO3) wafers are engineered for high-density holographic information storage applications. These single crystal wafers leverage lithium tantalate's exceptional electro-optic, acousto-optic, piezoelectric, thermal-optic, and photorefractive properties to enable advanced optical modulation, recording, and frequency conversion capabilities.

Frequently Asked Questions
What are the products you mainly work on?
We specialize in piezoelectric 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 quartz wafer supplier, exporting 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 services and can fabricate wafers according to your specifications. Our experienced team can provide technical recommendations if you're uncertain about your requirements. We also maintain standard wafer inventory for immediate availability.
Can you deliver the goods via our courier agent?
We can ship using your preferred courier service (DHL, FedEx, UPS, etc.) via your account. We optimize packaging to minimize shipping costs while ensuring product safety. Alternatively, we can arrange shipping using our established relationships with international courier companies.
How can you guarantee we get what we want safely?
We employ specialized packaging with adequate cushioning and buffer sponge to protect fragile wafers during transit. All packages are clearly marked as fragile. In case of damage during shipping, please follow our acceptance check procedure: document the condition before removing products from packaging and contact us immediately for resolution.
Acceptance Check Procedure
