Vacuum Fiber Optic Feedthroughs with Adapter

Request for Quotation

Thank you for using our services

Hermetic fiber feedthroughs with adapter interface FC and SMA have been designed, manufactured and tested in SQS. Fiber optic feedthrough assemblies are fully demountable, i.e. feedthroughs can be easily replaced.

With the help of hermetically sealed optical feedthroughs, it is possible to get optical signals in (or out of) vacuum chambers. Adapter feedthroughs ensure hermeticity up to 10^-12 mbar.l/s in HV and UHV environment.

Feedthroughs are available with various types of SM or MM fibers. Special custom designs e.g. or multichannel feedthroughs within one flange are available on request.

Design:

wide temperature range
UHV Compatible
SM or MM fiber
variety of flange types (KF, CF, custom requirement)
FC/PC, FC/APC, SMA

Applications:

temperature rooms
vacuum chambers
