LiNbO₃ wafer is a compound wafer composed of niobium, lithium and oxygen. It is a negative crystal with high spontaneous polarization characteristics, and the spontaneous polarization value can reach 0.70C/m² at room temperature. In addition, it is also the ferroelectric with the highest Curie temperature discovered so far, with a Curie temperature of 1210℃. Due to its unique physical and chemical properties, this material has broad application prospects in many fields and is one of the indispensable important materials in modern science and technology.

1. High-purity materials:

Optical Grade LiNbO₃ Wafer uses high-purity LiNbO₃ as the substrate, with a purity of more than 99.99%. This high-purity material can effectively reduce the impact of impurities on performance and ensure the stability of the optical and electrical properties of the wafer. According to industry standards, high-purity LiNbO₃ wafers can provide better light transmittance and lower absorption loss in optical applications, meeting the needs of high-end optical equipment.

2. Precise size control:

The diameter of the LiNbO3 Wafer is 2 inches, 3 inches and 4 inches, and the diameter tolerance is controlled within ±0.03mm. This precise size control meets the strict standards of the semiconductor industry and can ensure the adaptability of the wafer during processing and assembly. For example, in the manufacture of photonic integrated chips, precise dimensions can ensure the precise alignment and efficient integration of chips and improve production yield.

3. Excellent Curie temperature:

The Curie temperature of Optical Grade LiNbO₃ Wafer is 1142±0.2℃. This high Curie temperature allows the wafer to maintain good ferroelectric properties in high temperature environments. In some application scenarios that require high temperature operation, such as high-temperature optical sensors, this high Curie temperature wafer can work stably and will not lose function due to temperature increase.

4. Multiple cutting angle options:

LiNbO3 Wafer provides multiple cutting angles such as X/Y/Z, and the cutting angle tolerance is ±0.005mm. This high-precision cutting angle control can meet the needs of different applications.
