Overview of infrared optical glass
Optical materials that can transmit infrared rays are called infrared optical materials. It is impossible for infrared optical materials to have transmission capability in the entire infrared band, and can only have a certain degree of transmission in a certain band of the infrared spectrum.

Optical glass

Infrared optical instruments began with spectroscopic instruments very early, and by the end of the 19th century, prism-type infrared spectrometers were available. However, the rapid development of infrared optical instruments has received attention from people during and after World War II. Due to the needs of military and national defense, infrared detection, tracking and navigation instruments have been developed. The main military applications of infrared technology include infrared night vision, infrared reconnaissance, photography, tracking, and missile guidance. The development of infrared technology mainly depends on the level of infrared optical materials and infrared detectors. At present, the focus of the research and development of infrared optical materials at home and abroad is the materials in the bands of 1~3μm, 3~5μm and 8~14μm. This is because the attenuation of infrared light in the atmosphere in the above-mentioned bands is very small (called atmospheric window) .
Quartz Glass

Optical Quartz Glass


Infrared optical materials can be divided into three categories: crystal, glass and hot-pressed polycrystalline materials according to their material form (internal structure), properties and preparation methods. Infrared optical quartz glass is an important infrared optical material with several major characteristics:

First, glass infrared materials can easily obtain high optical uniformity, and can be used to manufacture large-size optical components with high optical requirements;

Second, glass materials will not cleavage, so they have higher mechanical strength, impact strength and greater surface hardness;

Third, most glass is stable to the atmosphere. In addition, the glass manufacturing and annealing process is relatively simpler and easier than the crystal growth and annealing process. Therefore, the cost is low and it is easy to make large, uniform optical products of various shapes. Infrared optical glass includes fused silica glass, various silicate infrared glasses, germanate glass, calcium aluminate glass, tellurate glass and arsenic-sulfur-smash, arsenic-sulphur-tellurium, germanium-arsenic-smash, Non-oxide system glass such as silicon-arsenic-tellurium, smash-arsenic, sulfur-arsenic, etc.

Optical Quartz Glass

Optical quartz glass has excellent spectral characteristics. It not only transmits infrared light, but also transmits ultraviolet light. The visible light transmission performance of optical quartz glass is very good. For some optical systems that require both visible light and infrared light to be transmitted, this type of glass is an ideal material. The spectral characteristic curve of domestic optical quartz glass is shown in Figure 14-30.

With the development of modern new technology, it is possible to produce completely bubble-free optical quartz glass. The optical uniformity, streaks, bubbles and other indicators are completely comparable to ordinary optical glass. At present, the domestic optical quartz glass grades are: JGS1 extreme ultraviolet optical quartz glass (application spectral band range of 185~2500nm); JGS2 ultraviolet optical quartz glass (application spectral band range of 220~2500nm); JGS3 infrared optical quartz glass (application spectral band range) 260~3500nm).

Due to the different production process methods, the transmittance of various light is different. For example, in ultraviolet optical quartz glass, due to the presence of hydroxide radicals, there is a large absorption peak at a wavelength of 2.8 mm. When producing infrared optical quartz glass, if a special dehydration process is used to prevent the glass from containing hydroxide radicals, the infrared absorption of hydroxide radicals can be eliminated, so that JGS3 infrared optical quartz glass has good transmittance in the infrared spectral region.

In the application of infrared technology, infrared direction finder, infrared camera, infrared commutator, infrared communication equipment, etc. equipped with infrared optical quartz glass lens, reflector and other optical components, precision optical quartz glass is used in various fields of national economy and military All have important uses.
