◆ Application Area
◇ Airborne/Shipborne Multispectral Observation System: Designed for infrared night vision devices, laser sights, etc., it maintains stability in low-temperature observation windows or in high-salt spray marine environments.
◇ Semiconductor manufacturing and inspection equipment: As substrate for epitaxy (such as in SOS technology) or as windows for lithography machines, they can withstand strong acid/strong alkali cleaning environments, and the crystal orientation accuracy is strictly controlled.
◇ Deep-sea probe observation window: Can withstand high pressure (>100 MPa) and salt corrosion environment, replacing traditional quartz glass to extend service life.
