High-quality metallized sapphire windows with AuSn soldering, designed for hermetic sealing in medical endoscopes and infrared optical systems.
Our AuSn solderable sapphire windows are widely used in medical endoscopes, infrared imaging, and hermetic optical packaging. The AuSn metallization ensures strong bonding with stainless steel housings, making them ideal for rigid endoscopes, surgical devices, and other high-reliability optical systems.
