Fused Silica Domes

A fused silica dome is a high-purity SiO₂ concentric spherical optical dome fabricated from bubble-free synthetic fused silica, available in JGS1, JGS2 and JGS3 grades. Compared with BK7 and borosilicate domes, it provides stable broadband light transmission ranging from deep UV to near-infrared wavelengths, featuring an ultra-low thermal expansion coefficient. Thanks to its excellent optical stability and environmental adaptability, fused silica domes are widely used for civilian optical systems that require continuous UV transmission, reliable performance under drastic temperature changes, and strong corrosion resistance.

The Applications of Fused Silica Domes

• Environmental & Meteorological Monitoring: All-sky imaging systems, atmospheric UV monitoring instruments, outdoor environmental detection equipment, and meteorological observation devices
• Marine & Underwater Civil Monitoring: Civil underwater camera protective domes, shallow and medium-depth marine monitoring equipment, underwater observation and shooting optical windows for civilian aquatic engineering
• Commercial Optoelectronics & Sensing: Civil optical sensor protection domes, UV detection equipment covers, commercial precision optoelectronic module protective windows
• Industrial & Laboratory Science: High-temperature industrial furnace observation windows, laboratory spectroscopic testing equipment, industrial UV monitoring and detection devices
• Commercial Outdoor Surveillance: High-temperature resistant industrial PTZ cameras, outdoor panoramic monitoring systems, weatherproof optical protective domes for civilian security equipment.
