Window (Weldable Sapphire Window)

Our company specializes in providing high-performance sapphire welding windows for premium medical endoscopes. As a critical optical and sealing component at the distal end of the endoscope, this window directly determines the device’s imaging quality, durability, and reliability. With an exceptionally broad transmission range—from visible light to near-infrared light (approximately >85%), it ensures clear imaging and true-to-life color reproduction without distortion. In specialized imaging modes such as fluorescence imaging, it minimizes background noise interference to the greatest extent possible, thereby enhancing the signal-to-noise ratio and improving image quality.
