When it comes to high-performance optical components, one of the most critical factors is how accurately and efficiently a material can transmit light. For cutting-edge scientific and industrial applications, you need a material that delivers stable, reliable performance even under the most demanding conditions. That material is quartz glass, a product we specialize in manufacturing.
In this article, we’ll explore the exceptional optical properties that set quartz glass apart and make it the ultimate material of choice for applications that depend on the mastery of light.
Unrivaled Transparency Across the Spectrum
The most remarkable feature of quartz glass is its incredibly wide transmission window. It demonstrates superior transparency across a broad spectrum, from the deep ultraviolet (DUV), through the entire visible range, and into the near-infrared (NIR) region.
This outstanding capability is due to its extremely high purity, consisting of over 99.99% silicon dioxide (SiO₂), which leaves virtually no impurities to absorb light. This property makes quartz glass an indispensable material for precision instruments and analytical equipment that rely on specialized light sources.
-
Ultraviolet (UV) Range: Its ability to transmit short-wavelength UV light—which is absorbed by most other types of glass—is crucial for fields like semiconductor lithography, UV sterilization equipment, and spectrophotometry.
-
Visible Range: In the visible spectrum, quartz provides a crystal-clear path for light, ensuring no color distortion and maximum signal transmission for windows, lenses, and viewports.
-
Infrared (IR) Range: Its transparency in the near-infrared makes it ideal for applications in fiber optics, IR sensors, and high-temperature process monitoring windows.
Optimized for Your Application: Our Three Optical Grades
Not all quartz glass is created equal. We manufacture distinct optical grades optimized for specific applications, ensuring you get the perfect performance for your project.
-
Far UV Grade (JGS1 / Synthetic Fused Silica)
This is our premier grade, offering the highest possible transmission performance in the demanding deep and far-ultraviolet spectrum. It transmits light clearly even at wavelengths as short as 185nm and is free from absorption bands in the UV-Vis range. JGS1 is the go-to choice for applications where ultimate purity and transmission are non-negotiable, such as excimer laser optics and advanced semiconductor inspection systems. -
UV Grade (JGS2 / Fused Quartz)
As our standard and most versatile grade, JGS2 offers a superb balance of high transmission and value across the UV and visible spectrums. It performs exceptionally well above 200nm, making it a reliable workhorse for a wide range of applications, including mercury lamp windows, chemical analysis instruments, and photochemical reactors. -
Infrared Grade (JGS3 / IR Quartz)
This grade is specifically engineered for maximum transparency in the visible and infrared regions. By virtually eliminating the hydroxyl (OH-group) content during manufacturing, we minimize absorption in the IR spectrum (around 2730nm). This makes JGS3 the perfect material for high-power IR laser components, high-temperature furnace viewports, and infrared-based inspection systems.
