High Vacuum Fiber Array 

       High Vacuum Fiber Array not only maintains the consistent high precision arrangement of Reful high-end fiber array, but also has excellent vacuum performance. Its housing adopts laser welding technology and is equipped with our company's vacuum feedthrough device developed specifically for high vacuum fiber arrays; its internal use of high temperature resistant, low outgassing glue, making the product leak rate up to 3.2*10-10Pa.m3/S level. It can help users to complete data acquisition with position information in vacuum environment; accurate and highly intensive energy transmission. Its compact size and high intensive energy transmission capability can be more advantageous in the narrow vacuum environment. Provide high performance optical transmission solution for vacuum field.
