Vacuum chamber, PECVD and coating machine sight window that isolates dust and process gases while withstanding high temperature and corrosive gas environments without contaminating chamber workpieces.
Light path sealing window for spectrometers and UV testing equipment, ensuring lossless light transmission for improved detection accuracy and measurement precision.
Observation viewport for tube furnaces and sintering furnaces, withstanding continuous 200-1100°C operation with resistance to thermal shock cracking.
Corrosion-resistant sight glass for reaction vessels and corrosive reaction equipment, resistant to HF and concentrated chemicals for real-time internal process observation.
Unlike borosilicate glass windows that are attacked by HF and degrade at high temperatures, this quartz window offers full HF resistance, sustained 1100°C operation, superior optical transmittance from double-sided polishing, low thermal expansion for thermal shock resistance, and high purity for contamination-free service in semiconductor and high-clean manufacturing environments.
