Fe doped Lithium Niobate Wafer Optical Grade and SAW Grade
Lithium Niobate (LiNbO3) is a useful optoelectronic material. The material not only has unique piezoelectric, optical and photoelastic properties, but also has good mechanical and chemical stability. Its combination of excellent electro-optic, acoustooptic and nonlinear optical properties makes it an attractive material in integrated optics.
BonTek provides up to 6" diameter LN doped wafers: Er:LN, MgO:LN and Fe:LN. The most used SAW orientations are YZ-cut and 128°Y-cut. The 128°Y-cut with X propagation is said to have the lowest spurious signal level.

FAQs:
- Q: What are the products you mainly work on?
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.
- Q: Can you accept product customization?
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.
Acceptance Check
- The product is fragile. We have adequately packed it and labeled it fragile. We deliver through excellent domestic and international express companies to ensure transportation quality.
- After receiving the goods, please handle with care and check whether the outer carton is in good condition. Carefully open the outer carton and check whether the packing boxes are in alignment. Take a picture before you take them out.
- Please open the vacuum package in a clean room when the products are to be applied.
- If the products are found damaged during courier, please take a picture or record a video immediately. DO NOT take the damaged products out of the packaging box! Contact us immediately and we will solve the problem well.
