Fused Silica Quartz Spheres Custom-Made for UV Lamps & Sensors

Fused Silica Quartz Spheres Custom-Made for UV Lamps & Sensors

Our Fused Silica Quartz Spheres Custom-Made for UV Lamps & Sensors are precision-engineered components designed for demanding optical and industrial environments. Manufactured from high-purity fused silica (SiO₂), these spheres offer exceptional UV transmittance, making them ideal for use in UV sterilization lamps, water treatment systems, and advanced photoelectric sensors.

Unlike standard glass, our custom quartz spheres exhibit near-zero fluorescence and can withstand extreme thermal shock, ensuring stable performance in high-temperature or high-intensity applications. Whether used as focusing lenses in UV curing systems or as critical float components in harsh chemical sensors, these spheres provide superior durability and optical clarity.

We offer complete customization to meet your exact specifications, including diameter tolerance (down to ±0.1mm), surface finish (polished or ground), and custom anti-reflective (AR) coatings. Available in various grades including UV-grade and optical-grade fused silica.

Partner with us for factory-direct pricing, rapid prototyping, and low minimum order quantities (MOQ). Request a quote today for custom quartz spheres tailored to your UV lamp or sensor project.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.

As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
