Q2: What is the difference between fused silica and fused quartz?
| Aspect | Fused Silica (Synthetic) | Fused Quartz (Natural) |
|---|---|---|
| Raw Material | Made from synthetic silicon compounds through flame hydrolysis or CVD technology | Processed from natural high-purity quartz crystals and silica sand |
| Purity Level | Ultra-high purity, metallic impurities are controlled at ppb level | High purity, impurities stay at ppm level, slightly lower than synthetic type |
| OH Content | 1000–2000 ppm | Less than 5–30 ppm after vacuum or electric melting |
| Optical Feature | Excellent deep ultraviolet transmission, the cut-off wavelength is about 170 nm | Better infrared transmission performance, relatively weak in deep ultraviolet band |
| Main Usage | Semiconductor lithography equipment, deep UV laser optical components | Infrared optical systems, long-term high-temperature industrial structural parts |
- What is the minimum order quantity for custom precision optical glass components?
FELIX OPTICAL GLASS offers highly flexible MOQs to support customer projects, including prototype testing, small-batch trial orders, and high-volume production. All products can be fully customized to your drawings, tolerances, and application standards. Please send us your specifications, and we will reply within 1-5 hours and provide an accurate quotation after careful evaluation within 1-2 days.
- Can I get free glass samples for testing before bulk order?
Yes, our FELIX GLASS factory supports sample testing for a wide range of precision optical glass components and assemblies. The lead time for sample production is 3 to 7 working days. Please contact us today to arrange samples and obtain a customized solution that meets your needs.
- What is the production lead time for custom optical glass components?
A: The production cycle for standard samples is 3-10 working days, while mass production requires 15-35 working days, depending on the complexity of the product and the order quantity. We provide reliable precision optical glass components and fast delivery services for orders from industries such as defense, industrial equipment, medical devices, shipbuilding, robotics, automotive, and aerospace. Please submit your project details so we can provide you with an accurate delivery schedule.
- Are your optical glass products ISO, CE and RoHS certified?
