IdealPhotonics' ultra-high vacuum fiber optic feedthrough flange is a sealed transition component that enables optical signals to cross a vacuum interface. Through metallized fiber sealing (leakage rate <10⁻¹² mbar·L/s) and radiation-resistant design, it maintains optical transmission (insertion loss <1dB) in a 10⁻⁹ mbar vacuum environment, making it suitable for optical monitoring and communication in extreme environments such as particle accelerators and space simulation chambers."Nanoscale sealed cross-boundary light transmission," through metal-ceramic gradient sealing technology (leakage rate <10⁻¹³ mbar·L/s) and fiber stress buffering structure, maintains stable optical path transmission (insertion loss fluctuation <0.2dB) under an extreme vacuum of 10⁻¹⁰ mbar, providing the ultimate solution for vacuum and optical connectivity for synchrotron radiation devices and quantum computing chip packaging.
