4 Inch LiNbO3 Wafer Polished 5mol% MgO Dope For Magnetic and
Optical Applications
Elevating Performance in Optical & Electronic Applications
Experience the next level of performance with our 5mol% MgO-Doped
LiNbO3 Wafers – the ultimate choice for demanding optical and
electronic applications. By precisely incorporating 5% magnesium
oxide into the lithium niobate lattice, we've crafted wafers that
offer unparalleled stability, enhanced optical properties, and
reduced darkening effects.
These wafers excel in high-speed data transmission, optical signal
processing, and frequency conversion, thanks to their outstanding
electro-optic and nonlinear optical coefficients. The MgO doping
further improves their resistance to photorefraction, making them
ideal for applications requiring long-term stability and high
optical quality.
Designed for precision and reliability, our 5mol% MgO-Doped LiNbO3
Wafers are the backbone of innovative optical modulators,
wavelength converters, and optical switches. Their exceptional
properties enable faster, more efficient, and more reliable
performance, empowering your devices to outperform the competition.
Upgrade your optical and electronic systems with 5mol% MgO-Doped
LiNbO3 Wafers. Embrace the future of technology and unlock the full
potential of your applications.

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.
- Q: Can you deliver the goods via our courier agent?
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.
- Q: How can you guarantee we get what we want safely?
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.
- Q: Can we visit your factory?
A: Sure. Factory inspection is important for large quantity
purchase and long-term cooperation. Face to face discussion is what
we mostly confident with. During the past years, big names around
the world have witnessed our progress in factory build-up. These
days, due to the Covid-19 pandemic, we also had the experience of
videoconferencing with global buyers.
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.
