As a kind of special industrial technology glass made of high purity silica, quartz plate has a series of excellent optical properties and physical properties. These properties make it widely used in many fields such as optical instruments, medical equipment, semiconductor manufacturing, etc. According to the optical properties of quartz plate, it can be mainly divided into three categories: far ultraviolet optical quartz glass (JGS1), ultraviolet optical quartz glass (JGS2) and infrared optical quartz glass (JGS3).

Far Ultraviolet Optical Quartz Glass (JGS1)

Far Ultraviolet Optical Quartz Glass JGS1 exhibits good transparency in the ultraviolet and visible spectral ranges. It has no absorption band in the 185-250 nanometer (nm) band range, which means it is able to transmit light efficiently in this band. Meanwhile, JGS1 has strong absorption bands in the 2600-2800 nanometer (nm) band range, a property that gives it a unique advantage in certain specific spectral analysis applications. JGS1 also has non-luminescence and light radiation stability, making it widely used in high-precision optical instruments and ultraviolet light source equipment.

Ultraviolet Optical Quartz Glass (JGS2)

Ultraviolet Optical Quartz Glass JGS2 also exhibits excellent transparency in the ultraviolet and visible spectral ranges. Compared to JGS1, JGS2 has no absorption band in the 200-250 nanometer (nm) band range, which is slightly different, making it more advantageous in some specific ultraviolet applications. In addition, JGS2 also has strong absorption bands in the 2600-2800 nanometer (nm) band range, and exhibits non-luminescence and light radiation stability. These properties make JGS2 widely used in ultraviolet light sources, optical filters, and ultraviolet spectroscopy instruments that require high light transmittance.

Infrared Optical Quartz Glass (JGS3)

Infrared Optics Quartz glass JGS3 is transparent in the visible and infrared spectral range, especially in the range of 2600-2800 nanometers (nm) without obvious absorption bands. This property gives it a unique advantage in infrared spectral analysis, infrared optical instruments, and infrared imaging equipment. JGS3's high light transmittance and stable physical properties make it an ideal material for infrared spectrometers, infrared cameras, and other equipment.

Spectral transmission properties of quartz plate

The spectral transmittance of quartz plate is influenced by several factors, including reflection, scattering, and absorption. The reflectivity of quartz glass is generally 8%, slightly higher in the ultraviolet region and slightly lower in the infrared region. Scattering has little effect on the transmittance of quartz glass and is usually negligible. Spectral absorption is closely related to the impurity content and production process of quartz glass. The transmittance in the band below 200 nanometers (nm) can reflect the amount of metal impurities, while the absorption at 240 nanometers (nm) is related to the amount of oxygen-deficient structure.

The absorption in the visible band is mainly caused by the presence of transition metal ions, while the absorption at 2730 nanometers (nm) is the absorption peak of hydroxyl groups, which can be used to calculate the hydroxyl content.

Other physical properties of quartz plate

In addition to excellent optical properties, quartz plates also have a series of excellent physical and chemical properties. For example, quartz glass has a softening point temperature of about 1730 ° C, which can be used for a long time at 1100 ° C, and the maximum use temperature for a short time can reach 1450 ° C. In addition, quartz glass has a very low coefficient of thermal expansion and good thermal stability, which can withstand severe temperature changes without bursting. Quartz glass also has good electrical insulation properties and corrosion resistance, especially except for hydrofluoric acid, which hardly reacts chemically with other acids.

Application of quartz plate

Due to its excellent optical and physical properties, quartz plates have been widely used in many fields. In the field of optics, quartz plates are commonly used to make high-precision optical instruments, ultraviolet light source equipment, infrared spectrometers, etc. In medical equipment, quartz plates are used to make optical lenses, filters, etc. In semiconductor manufacturing, quartz plates are used to make wafer packaging materials, photomasks, etc. In addition, quartz plates are also widely used in architectural decoration, artificial stone, electronic chip packaging, and other fields.

Quartz plates can be divided into far ultraviolet optical quartz glass (JGS1), ultraviolet optical quartz glass (JGS2) and infrared optical quartz glass (JGS3) according to their optical properties. These different types of quartz plates exhibit unique optical and physical properties in their respective application fields, providing strong support for the development of related industries.
