Vacuum Feedthroughs

Vacuum Feedthrough_Header

Vacuum feedthroughs allow optical fibers to pass through a vacuum chamber’s wall while maintaining a seal.  Coastal Connections specializes in building custom feedthroughs with multiple fibers reducing your risk of a vacuum leak.  Our proprietary fiber sealing technology does not add stress to the fiber allowing for sealing on bend sensitive fibers.  The only company in the world that sells multichannel feedthroughs with polarization maintaining fibers.
