Optical Grade Quartz Wafers

Optical grade quartz wafers can be supplied in a variety of cuts like X-cut, Y-cut, Z-cut, and in diameters up to 100mm. Optical grade QZ wafers transmit the light in deep UV to near IR range and therefore are good for use in optics, spectroscopy, laser and microfluidics.

Optical grade quartz wafers are a type of high-purity quartz material that is used in the manufacturing of optical components such as lenses, mirrors, and prisms. These wafers are typically made from fused quartz, which is a high-purity glass made from silicon dioxide that has been melted and then rapidly cooled to form a solid.

Optical grade quartz wafers have several key characteristics that make them ideal for use in optical applications. First, they have excellent optical properties, including high transparency, low birefringence, and low absorption of light. This allows for high-quality transmission of light through the material, which is critical for optical components.

Second, optical grade quartz wafers have a high degree of dimensional stability, meaning that they maintain their shape and size even when exposed to changes in temperature or humidity. This is important for maintaining the precise dimensions required for optical components, which must be extremely accurate to function properly.

Finally, optical grade quartz wafers have high resistance to chemical and thermal damage, making them durable and long-lasting. This makes them ideal for use in harsh environments where other materials may be damaged or degraded over time.
