X-cut and Z-cut LiNbO3 wafer 8 inch Large Size For Optical Use
Lithium niobate is transparent between 0.25 and 5.3 μm. It can be used in visible, near IR and middle IR region. It should be noted that non-doped lithium niobate exhibits high photorefraction. Therefore in high-power laser applications, magnesium oxide-doped crystals (MgO:LiNbO3) are used. They have a higher Laser Damage Threshold. At the same time, the doping has no effect on the optical properties of the crystal.
BonTek is among the very first who can provide 8 inch LiNbO3 wafers for X-cut and Z-cut. For 6 inch LiNbO3 wafers, all cut angles are possible!

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.
