How Is The Light Transmittance of Quartz Glass

Quartz glass is a special industrial technology glass composed of single silica (SiO2). Due to its unique physical and chemical properties, it has a wide range of applications in many fields. Among them, the light transmittance of quartz glass is one of its most significant and important characteristics. This article will discuss the light transmittance of quartz glass in detail, including its transmittance in different spectral bands, influencing factors and practical applications.


The practical application of quartz glass transparency


Overview of Light Transmittance of Quartz Glass

Quartz glass has excellent light transmittance due to its high purity and compact microstructure. Quartz glass exhibits good light transmittance in the entire spectral band from ultraviolet to infrared. Specifically, the visible light transmittance of quartz glass is usually above 85%, and some high-quality quartz glass can even achieve a transmittance of more than 93%. In the ultraviolet spectrum, the transmittance of quartz glass also performs well, with a maximum transmittance of more than 80%.

Spectral Characteristics of Light Transmittance of Quartz Glass

The light transmittance of quartz glass is not limited to the visible light region, but also has excellent transmission properties in the ultraviolet and infrared regions. In the 185-2500nm band, quartz glass has no absorption band and exhibits good transparency. In the 2600-2800nm band, although there is a strong absorption band, the overall transmittance of quartz glass in the infrared spectrum is still high. This wide-spectrum light transmittance makes quartz glass have a wide range of application prospects in many fields.

Factors Affecting the Transmittance of Quartz Glass

The light transmittance of quartz glass is affected by a variety of factors, including the following aspects:

Purity: The purity of quartz glass has a significant impact on its light transmittance. High-purity quartz glass has fewer impurities and defects, thus reducing light scattering and absorption and improving light transmittance.

Microstructure: The microstructure of quartz glass also has a significant impact on its light transmittance. A compact microstructure can reduce light scattering and improve light transmittance.

Surface quality: The surface quality of quartz glass also affects its light transmittance. Rough or scratched quartz glass increases light scattering and decreases light transmittance.

Spectral bands: The transmittance of light in quartz glass varies in different spectral bands. For example, in the ultraviolet spectrum, the transmittance of quartz glass is usually higher; in the infrared spectrum, although there is a strong absorption band, the overall transmittance is still higher.

Practical Application of Light Transmittance of Quartz Glass

Quartz glass is widely used in many fields due to its excellent light transmittance. Here are some typical application scenarios:

Laboratory equipment: Due to its high light transmittance and chemical stability, quartz glass is commonly used in laboratory equipment, such as spectrophotometers and spectrometers.

Special high-purity product refining equipment: In the refining process of special high-purity products, quartz glass is often used in reactors, distillation towers, and other equipment due to its high light transmittance and corrosion resistance.

Spaceship and wind tunnel windows: The high light transmittance and radiation resistance of quartz glass make it an ideal material for extreme environments such as spacecraft and wind tunnel windows.

Optical system: The high light transmittance and low dispersion of quartz glass make it an important material in optical systems, such as telescopes and microscopes.


Detailed explanation of the transparency of quartz glass


Quartz glass has a wide range of application prospects in many fields due to its excellent light transmittance. Its high light transmittance is mainly due to its high purity and tight microstructure. In practical applications, the light transmittance of quartz glass is affected by various factors such as purity, microstructure, surface quality and spectral band. By optimizing these factors, the light transmittance of quartz glass can be further improved to meet the needs of more fields.
