Leading the Optical Revolution: Exploring the Superior Properties and Applications of Quartz Glass

In today's rapidly advancing technological landscape, optical technology has become a crucial driving force behind innovation. Quartz glass, with its exceptional optical properties, is spearheading a revolution in the field of optics. This article delves into the five core attributes of quartz glass and how these properties make it the ideal material for manufacturing high-precision optical instruments and components.

Optical Properties

High Transmittance, Low Dispersion, High Refractive Index Quartz glass stands out in the optical field due to its superior optical characteristics. It boasts a transmittance of over 90% in the visible light range, approaching theoretical limits, and also has high transmittance in both ultraviolet (UV) and infrared (IR) regions. This makes quartz glass highly suitable for various optical instruments and components, such as optical sensors. Additionally, quartz glass has a low dispersion coefficient, approximately one-third that of ordinary optical glass. This means that during imaging, the difference in refraction angles for different wavelengths of light is minimized, reducing chromatic aberration and improving image quality. This property makes quartz glass an ideal material for cameras, camcorders, and other optical imaging devices. With a refractive index of around 1.45, quartz glass enables the production of lenses with high magnification and numerical aperture, resulting in smaller, lighter, and higher-performing optical components. Our low-dispersion quartz glass microscope lenses and high-precision quartz glass optical lenses perfectly exemplify these capabilities.

Thermal Properties

Excellent Thermal Stability and High-Temperature Resistance Quartz glass exhibits an extremely low coefficient of thermal expansion, only 1/10 to 1/20 that of ordinary glass, with a linear expansion coefficient of approximately 5.5*10⁻⁷. This gives quartz glass excellent thermal shock resistance, maintaining stable optical properties such as transmittance, refractive index, and dispersion in high-temperature environments. Our quartz glass windows for infrared spectroscopy and quartz glass windows for UV spectrometers are prime examples of this attribute. The softening point of quartz glass is around 1730°C, allowing it to be used for extended periods at temperatures up to 1100°C and short-term exposure to temperatures as high as 1450°C. This makes quartz glass ideal for laboratory equipment and other applications requiring high-temperature resistance.

Chemical Properties

Outstanding Corrosion Resistance Quartz glass is an acidic material, inert to all acids except hydrofluoric acid and hot phosphoric acid. At room temperature, alkalis and salts have minimal corrosive effects on quartz glass, with transparent quartz glass exhibiting better chemical stability than opaque quartz glass. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Our medical-grade quartz glass optical fibers and industrial laser transmission quartz glass fibers benefit greatly from this property.

Electrical Properties

Superior Electrical Insulation Quartz glass has a resistance value that is 10,000 times higher than ordinary glass, making it an excellent electrical insulator. Even under high temperature, high pressure, and high-frequency conditions, quartz glass maintains high dielectric strength and resistance with virtually no dielectric loss. This makes quartz glass a preferred material for high-temperature dielectric insulation in various electrical and high-frequency applications.

Mechanical Properties

High Hardness and Durability Quartz glass has a very high hardness, which, although making it challenging to process, also means it has excellent wear resistance and scratch resistance. Our high-power laser quartz glass cavities, laser resonator quartz glass components, and beam shaping quartz glass laser elements leverage these properties to deliver outstanding performance.
