Micro Window

Micro window is a kind of miniaturized optical window, which is usually made of high-quality optical materials (such as fused silica, sapphire, optical glass, etc.), with extremely small size, excellent surface quality, , and specific optical transmission characteristics. They play a small but crucial role in high-tech fields such as semiconductors, communications, sensing, healthcare, analysis, and defense, making it possible to achieve high-precision optical observation, signal transmission, and energy transfer in harsh or isolated environments.
