What are the optical characteristics of fused silica glass tubes

The fused silica glass tube, as an inorganic glass material made of high-purity silicon dioxide (SiO2) through high-temperature melting and crystallization, has excellent optical properties. These characteristics have made it widely used in various fields such as optical instruments, optical communication, semiconductors, etc.

1、 High transparency

The fused silica glass tube has extremely high light transmittance, and its light transmittance is more than 85%. It exhibits good transparency throughout the entire spectral range from ultraviolet to infrared. Especially in the visible light band, its transmittance can reach over 95%, and in the ultraviolet spectral region, the transmittance can also reach over 80%. This high transmittance makes fused silica glass tube an ideal material for manufacturing high-precision optical instruments and optical devices.

2、 Low dispersion characteristics

Dispersion is the phenomenon where light of different wavelengths has different refractive indices when propagating in a medium. The fused silica glass tube has low dispersion, that is, in the process of light propagation, light of different wavelengths has similar refractive index. This characteristic makes fused silica glass tube of great significance in manufacturing optical prisms and lenses. It can ensure that light maintains high clarity during propagation, avoiding image blurring or distortion caused by dispersion.

3、 UV resistance performance

The fused silica glass tube also has good ultraviolet resistance. It can effectively resist the erosion of ultraviolet rays and maintain the stability of optical performance. This characteristic makes fused silica glass tube have important application value in the field of ultraviolet spectrum processing and analysis. For example, fused silica glass tubes play a key role in the manufacture of ultraviolet sterilization lamps, ultraviolet detectors and other equipment.

4、 High refractive index

Fused silica glass tube has a high refractive index, which makes it able to produce a stronger refractive effect in the optical system. A high refractive index helps with the propagation and focusing of light in a medium, thereby improving the performance of optical systems. This characteristic makes fused silica glass tubes have significant advantages in manufacturing high-precision optical lenses, optical fiber connectors and other optical devices.

5、 Chemical stability and high temperature resistance

In addition to the above optical properties, fused silica glass tubes also have excellent chemical stability and high temperature resistance. It hardly reacts chemically with other acidic substances (except hydrofluoric acid) and can maintain optical stability at high temperatures. These characteristics enable the fused silica glass tube to maintain good optical properties in harsh environments, thus expanding its application range.

6、 Application Fields

Based on the above optical characteristics, fused silica glass tubes have been widely used in many fields. For example, in optical instrument manufacturing, it is used to manufacture high-precision optical lenses, optical prisms, and lenses, etc; In the field of optical communication, it is used to manufacture fiber optic connectors, optical waveguides, etc; In semiconductor manufacturing, it is used to manufacture photolithography masks, diffusion tubes, etc. In addition, fused silica glass tubes are also widely used in military industry, metallurgy, building materials, chemistry, machinery, power, environmental protection and other fields.

Fused silica glass tube shows a broad application prospect in many fields because of its excellent optical properties.
