Lithium Tantalate Wafer Electro-Optics, Acousto-Optics used in Telecom Mobile Phone Market
LiTaO3 (LT) optical crystal is a kind of transparent crystal with piezoelectric, electro-optic, acoustooptic and nonlinear optical effects. It is an excellent material for acoustic transmission medium and high frequency transducer. LT crystals can be widely used in electro-optic devices, laser frequency multiplier and acousto-optic devices.
Application: surface acoustic wave filter, resonator, Q-switch, optical modulator, acoustooptic switch, laser frequency doubling, optical parametric oscillator, optical storage, high temperature and high frequency ultrasonic detector, infrared detector and optical pickup device.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
