Ultra-high Vacuum Fiber Feedthrough VFT Vacuum Through Tube Fiber Through Interface Can be Customized
The VFTT ultra-high vacuum fiber feedthrough adopts welding type or integrated structure, and its sealing performance is more, allowing the vacuum level to be as low as 1 × 10-10 Torr, and can be used at temperatures up to 250 °C. VFTT includes two transmission ranges of multi-mode fiber, ultraviolet light/visible light: 200~800 nm, visible light/near infrared: 400~2200 nm. In addition, it can also be customized according to customer needs.

This product can use various flanges of CF KF ISO series, and can also be customized according to customer requirements.
The optical fiber connectors at both ends are conventional SMA905, FC, ST, etc., and can also be customized according to customer requirements. The flange dimensions can also be customized. Please contact us.
It is compatible with our vacuum multi-mode fiber optic patch cords, allowing users to couple light from the external environment to a vacuum chamber through fiber optic cables. When using fiber optic patch cords in a vacuum environment, please ensure that the cables are compatible with vacuum (it is recommended to match with TaoLab Vacuum fiber).
