Combined Vacuum Fiber Feedthroughs

Our combined-interface feedthroughs let you choose pigtail and adapter orientation on demand. The feedthrough seal supports most fiber types—including polarization-maintaining—and installs in a standard or customized flange alongside any other feedthrough. Offered with or without flange.

Pigtailed variants accommodate a wide range of fibers and connectors (FC/PC, FC/APC or SMA 905) on either the vacuum or air side. Machined from UHV-compatible materials and sealed via proven processes, they perform reliably in high and ultra-high vacuums. Feedthroughs can be removed from the flange for easy maintenance or reconfiguration.

Advantages

• Configurable combined pigtail & adapter orientation
