Optics SiC Wafer Manufacturer

As a reliable and stable SiC Wafer Manufacturer, we can provide high purity SiC Wafer for Optics(AR/VR) application. Both 6inch and 8inch are available in our company. We offer more than just wafers, we provide full technical support. HPSI SiC Wafer have emerged as a novel material for AR optical lenses due to their high refractive index and high transmittance:

Application Value: With a refractive index of approximately 2.6—higher than that of conventional optical glass (around 1.5)—SiC enables the reduction of optical module size in AR glasses (by decreasing the number of lenses), thereby improving wearing comfort. Additionally, its high thermal conductivity helps prevent lens fogging caused by device heating, further enhancing the user experience.

Optics AR/VR SiC Wafer Basic Spec

Conventional optical glass, with a refractive index of only 1.7–1.8, limits the design possibilities of optical waveguides, making it difficult to balance clarity, field of view (FOV), and lens thickness. In contrast, silicon carbide (SiC)—a power semiconductor material widely used in new energy vehicles and industrial power supplies—is now gaining prominence as a high-performance substrate for AR optical waveguides. This is primarily due to the following properties of SiC:

• High refractive index (2.6–2.7): Enables more compact grating design and improves the field of view (FOV).

• High hardness and thermal conductivity: Suitable for complex processing and high-temperature environments, ensuring wearing safety.

• Strong optical stability: Eliminates rainbow artifacts and delivers clearer image quality.

• Lightweight and thin design: With a lens thickness of only 0.55 mm and a single-piece weight of just 2.7 g, it significantly enhances wearing comfort in finished AR glasses.
