الأسئلة الشائعة
Q: What is a quartz glass dome used for?
A: Quartz glass domes are primarily used in applications requiring high UV transmission, thermal stability, and optical clarity. Common applications include solar concentrators, UV disinfection systems, photocatalytic reactors, optical instruments, and high-temperature viewing windows. Their ability to transmit UV-C wavelengths makes them ideal for germicidal applications.
Q: Can quartz domes transmit UV-C light?
A: Yes, high-purity quartz glass domes transmit 80-90% of UV-C light (100-280 nm wavelength), making them suitable for germicidal applications. Unlike borosilicate glass which blocks virtually all UV-C, quartz glass enables efficient transmission of these shorter wavelengths critical for microbial disinfection and advanced photochemical processes.
Q: How durable are quartz domes in high-temperature environments?
A: Quartz glass domes maintain structural integrity and optical properties at temperatures up to 1200°C, far exceeding the typical requirements of solar concentrator applications (450°C). They feature low thermal expansion (≤5.5×10⁻⁷ /°C), excellent thermal shock resistance, and do not devitrify or cloud under prolonged high-temperature exposure.
Q: What coatings can be applied to quartz domes for UV applications?
A: For UV applications, TiO₂ photocatalytic coatings are commonly applied to quartz domes. These coatings enhance photocatalytic reactions for pollutant degradation in water treatment systems. We can apply TiO₂ coatings to either the inner or outer surfaces of the dome depending on your application requirements. Anti-reflective (AR) coatings are also available to minimize light loss and improve system efficiency.
Q: What dimensional tolerances are achievable for quartz optical domes?
A: Our standard manufacturing capabilities for quartz domes include dimensional tolerances of ±0.1mm. For precision optical applications, we can achieve tolerances down to ±0.05mm on diameter, thickness, and sphericity. Surface quality standards typically range from 80-50 to 60-40 scratch-dig, with higher precision available for specialized optical applications.
