Transparent quartz rod, also known as quartz light guide rod or quartz fiber rod, is an optical transmission material used for optical transmission. It is usually made of high-purity quartz glass, with excellent optical properties and chemical stability.

The shape of the quartz rod can be straight or semi-circular. The semi-circular light guide rod is usually cut from a cylindrical body with a larger diameter along the vertical direction, similar to half of a cylinder. This shape allows the light to enter from one end face, then propagate along the surface of the rod, and finally output from the other end face.

The quartz rod has excellent light transmission performance, which can effectively transmit light to a long distance. It also has low light loss, high refractive index, and small dispersion, making it widely used in optical communication, optical sensing, and medical equipment.

The manufacturing process of the quartz rod usually includes material selection, melting, drawing, and cutting. In the melting process, high-purity quartz raw materials are heated to a high temperature to form a molten quartz liquid. Then, through drawing and cutting processes, the molten quartz liquid is formed into the required shape of the quartz rod.

In summary, transparent quartz rod is a high-quality optical transmission material with a wide range of applications. It can be used in optical transmission, optical sensing, optical communication, and other fields, providing high-quality optical performance for these applications.
