Optical Feedthroughs

19 Aug 2021

LASER COMPONENTS supplies fibre optic feedthroughs which allow optical signals to be easily delivered from one environment to another while preventing any leakage from one side of the barrier to the other side.

Both sides can be different, for example one side can be high-pressure (up to 1000 bars), while the other side high vacuum.  They can also withstand high temperatures such as +600°C or extremely cold temperatures such as 0.5 K, they can also endure corrosive or radioactive environments.

We have a large product range with PM, SM and MM fibres suited for high-vacuum (HV) and ultra-high vacuum (UHV) down to as little as 10–8 mbar l/s.  These products are also suitable for high-pressure, up to 1000 bars.  Thanks to different sizes such as CF and KF flanges, our feedthroughs can be easily and steadily mounted on a chamber wall.

These hermetic fibre optic feedthroughs are available in two main configurations:

Bulkhead style equipped with standard FC/PC, FC/APC or SMA connectors where the fibres can be replaced and Inline style having no connector at the flange, but pigtails terminated with connectors.  The latter solution allows high packing densities of multiple fibres, at a good price/performance ratio.

Some of our hermetic feedthroughs have the advantage of being reconfigurable, meaning that they can be disassembled, reconfigured, and reused for a different application, customization is also available.
