Vacuum Fiber Optics Components

Accu-Glass Products line of Fiber Optic Components, including Feedthroughs and Cable Assemblies.

Our UHV Fiber Optic feedthroughs are hermetically sealed into a stainless steel shell, using the latest in glass bonding technology.  

Our proprietary seal allows for the broadest temperature range of any fiber feedthrough available today:  From -269°C to +250°C.
