What Is The Difference Between SAW Grade LiNbO3 Wafers and Optical Grade LiNbO3 Wafers?

Optical grade lithium niobate is a low-strain, impurity-free crystal material grown from the best raw materials at a relatively slow growth rate and is commonly used in optical applications that require the highest quality. Optical grade lithium niobate wafers are widely used in optical devices with high-performance requirements. 

SAW grade lithium niobate is mainly used for surface acoustic wave applications, and its growth raw material is second only to optical grade growth raw material, with a faster growth rate than optical grade lithium niobate, which facilitates mass production and cost-effectiveness. 

In general, these grades of lithium niobate differ slightly in terms of material quality and usage, with optical grade lithium niobate considered to be of the highest quality while SAW grade lithium niobate has a relatively lower price.

Key Characteristics of Lithium Niobate Wafers(LiNbO3 Wafers)

The main characteristics of lithium niobate wafers are their excellent electrical properties and thermal stability.

FAQS about SAW&Optical Grade Lithium Niobate Wafers

What Is The Pyroelectric Free Black LiNbO3 Wafers?

We use reduction technique to produce pyroelectric free black LiNbO3 wafers, which has a high ability to neutralize charges even if the electric potential occurs instantaneously. The pyroelectric effect of black LiNbO3 wafers is almost eliminated and the transmittance is significantly reduced. The piezoelectric properties of black lithium niobate wafers are no different from those of standard wafers. Therefore, black reduced lithium niobate wafers are widely used to produce higher frequency surface acoustic wave devices.

What Devices Can LiNbO3 Wafers Be Used To Manufacture?

LiNbO3 wafers can be used to manufacture Q-switching devices, high-performance gyroscope, accelerators and accelerometer sensors, MEMS devices, surfaced acoustic devices and so on.
