4 inch LiTaO3 black Fe doped Lithium Tantalate MEMS Wafer
Lithium tantalate has good piezoelectric, ferroelectric, acoustooptic and electro-optic effects. It is widely used in resonators, filters, transducers and high frequency surface acoustic devices.
Crystro's Fe:LiTaO3 is grown by Czochralski method.Max diameter reach 6inch,can offer kinds of size per required.
Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.We looking forward to meet you.
