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

Frequently Asked Questions
What are the products you mainly work on?
We are piezoelectric 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 in 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 needed. We also maintain standard wafer inventory for immediate availability.
Can you deliver the goods via our courier agent?
Yes, 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. We also offer freight management services with discounted international shipping rates.
How can you guarantee we get what we want safely?
We use specialized packaging with buffer materials and fragile labeling. For acceptance verification, please follow these steps: Check outer carton condition upon receipt, photograph packaging before removal, open vacuum packages in clean room environments only. If damage occurs during transit, document immediately without removing from packaging and contact us for resolution.
Acceptance Check Procedure
- Products are fragile and adequately packed with fragile labeling
- Handle with care and verify outer carton condition upon receipt
- Photograph packaging alignment before removing contents
- Open vacuum packages only in clean room environments
- If damage is found, document immediately and contact us without removing products from packaging
