What are the properties and applications of optical quartz glass

Optical materials that can transmit infrared light are called infrared optical materials. Infrared optical materials can not have the ability to transmit in the entire infrared band, only in a certain band of the infrared spectrum has a certain transmission properties.

Optical materials that can transmit infrared light are called infrared optical materials. Infrared optical materials can not have the ability to transmit in the entire infrared band, only a certain band of the infrared spectrum has certain transmission properties.

Infrared optical instruments started from spectroscopic instruments at an early stage, and due to the needs of military defense, infrared detection, tracking, and navigation instruments began to be 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, domestic and foreign infrared optical materials research and development focus on 1 ~ 3μm, 3 ~ 5μm, and 8 ~ 14μm of the band materials, because the above band of infrared light attenuation in the atmosphere is very small (called the atmospheric window).

Infrared optical materials can be categorized into three main groups: crystalline materials, glass materials, and hot-pressed polycrystalline materials according to their morphology (internal structure), properties, and preparation methods. Quartz glass for infrared optics is an important infrared optical material with several characteristics:
1. Glass infrared materials are easy to obtain high optical uniformity, and can be used to manufacture large-size optical components with high optical requirements;
2. glass-like materials do not disintegrate and, therefore, have high mechanical strength, impact strength, and large surface hardness;
3. most glasses are stable to atmospheric action. Third, most glasses are stable to atmospheric action. In addition, the manufacturing and annealing of glass is relatively simple and easy compared to the cultivation and annealing of crystals. As a result, it is inexpensive and easy to produce large, homogeneous optical products of various shapes. Infrared optical glass includes fused silica glass, various silicate infrared glasses, and so on.

With the recent development of new technology, can be produced completely bubble-free optical quartz glass, optical uniformity, streaks, bubbles, and other indicators, fully comparable with the general optical glass. At present, the domestic optical quartz glass grades are JGS1 far-ultraviolet optical quartz glass (application of the spectral band range of 185 ~ 2500nm); JGS2 ultraviolet optical quartz glass (application of the spectral band range of 220 ~ 2500nm); JGS3 infrared optical quartz glass (application of the spectral band range of 260 ~ 3500nm).

Different production methods result in different transmittances for various types of light. For example, in the ultraviolet optical quartz glass, due to the presence of hydroxide, there is a large absorption peak at a wavelength of 2. 8Mm. Production of infrared optical quartz glass, such as the use of a specialized dehydration process, so that the glass does not contain hydroxide, can eliminate the infrared absorption of hydroxide, so that the JGS3 infrared optical quartz glass in the infrared spectral region has a good transmittance.

Optical fused silica is a high-performance material that is widely used in the manufacturing of various optical components, including Infrared Optical Quartz Glass Lenses, Infrared Cameras, and Infrared Communication Equipment. This unique material is prized for its excellent optical properties, high thermal stability, and resistance to thermal shock and chemical corrosion.
Infrared Optical Quartz Glass Lenses made from optical fused silica offer superior clarity and precision, making them ideal for use in a wide range of applications. These lenses are commonly used in infrared imaging systems, medical devices, scientific instruments, and industrial equipment. With their high transmission in the infrared spectrum, optical quartz glass lenses provide exceptional performance in capturing and transmitting infrared radiation, allowing for crisp and clear images to be produced.

Infrared Cameras are another important application of optical fused silica. These cameras are used in various industries, including security, surveillance, and thermal imaging. The use of optical fused silica in the manufacturing of infrared camera lenses ensures high optical performance, excellent thermal stability, and durability. These lenses are capable of capturing infrared radiation with high sensitivity and accuracy, allowing for precise thermal imaging and analysis in a variety of environments.

Infrared Communication Equipment also benefits from the superior properties of optical fused silica. Components such as optical fibers and windows made from this material are essential for the transmission of infrared signals in various communication systems. Optical fused silica offers low optical losses, high transmission rates, and exceptional durability, making it a preferred choice for use in infrared communication equipment. This allows for efficient and reliable data transmission in infrared communication networks, ensuring high-quality performance and reliability.

One of the key advantages of optical fused silica is its high thermal stability, which allows it to withstand extreme temperatures without compromising its optical properties. This makes it an ideal material for use in applications where thermal fluctuations are common, such as in infrared imaging systems and communication equipment. Optical fused silica is also highly resistant to chemical corrosion, ensuring long-term reliability and durability in harsh operating environments.

Overall, optical fused silica is a versatile and high-performance material that is essential for the production of Infrared Optical Quartz Glass Lenses, Infrared Cameras, and Infrared Communication Equipment. Its exceptional optical properties, thermal stability, and resistance to thermal shock and chemical corrosion make it a preferred choice for use in a wide range of infrared applications. Whether used in imaging systems, communication equipment, or other optical devices, optical fused silica delivers unmatched performance and reliability, making it an indispensable material in the field of infrared optics.
