8 Inch 12 Inch Fused Quartz JGS1 Wafers For Optics Lasers And Semiconductors
Fused Quartz JGS1 Features
Fused quartz JGS1 is a high-quality synthetic quartz glass known for its excellent optical properties and thermal stability. It is widely used in various industries, including optics, lasers, semiconductors, and scientific research. JGS1 is specifically designed to provide exceptional transparency in the ultraviolet (UV) to infrared (IR) range, making it suitable for a broad range of optical applications.
One of the key features of JGS1 is its high purity. It is composed primarily of silicon dioxide (SiO2), ensuring minimal impurities and excellent optical transmission. This purity allows JGS1 to maintain its optical clarity and performance over a wide wavelength range.
Another important characteristic of JGS1 is its thermal stability. It has a low coefficient of thermal expansion, which means it can withstand rapid temperature changes without cracking or distortion. This property is essential in applications that involve high temperatures or thermal cycling, such as in lasers and scientific instruments.
JGS1 also exhibits excellent chemical resistance, making it highly resistant to most acids, alkalis, and organic solvents. This resistance to chemical attack allows JGS1 to withstand harsh chemical environments, making it suitable for applications that require exposure to corrosive substances.
Fused Quartz JGS1 Manufacturing Process
The manufacturing process of JGS1 involves melting high-purity quartz crystal and carefully controlling the cooling and annealing processes to achieve the desired optical and mechanical properties. This precise manufacturing technique ensures the uniformity and quality of the final product.
Fused Quartz JGS1 Applications
Due to its outstanding optical and thermal properties, JGS1 finds applications in a wide range of industries. It is commonly used in optics for lenses, windows, prisms, and mirrors, providing high-quality optical components for various imaging and light manipulation systems. In laser systems, JGS1 serves as laser windows, cavities, and beam delivery components, thanks to its excellent optical transmission and thermal stability. In the semiconductor industry, JGS1 is utilized in fabrication processes such as diffusion tubes and wafer carriers, benefiting from its chemical resistance and low contamination properties. Additionally, JGS1 finds use in scientific instruments, UV curing systems, and other applications that require high-performance optical materials.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
