Hermetic Fibre Feedthroughs for Cryogenic Environments

Working in cryogenic environments is challenging, but a lot of cutting-edge research, such as quantum computing and material science, requires operating in these extreme setups. Light is often utilized to probe and interact with experimental setups inside a cryogenic chamber, with applications ranging from trapping atoms or ions to performing spectroscopic measurements. Consequently, a reliable optical connection between the cryogenic and room temperature environments is necessary.

Standard fibre optic cables designed for telecommunications applications are generally unsuitable for cryogenic environments. Special coatings are required to ensure optimal performance, adding a layer of complexity in sourcing suitable components. Additionally, these setups often operate at low pressures, meaning any feedthrough needs to provide a high level of hermeticity.

LASER COMPONENTS can address these needs with specially designed fibre feedthroughs and cable assemblies for extreme environments. From ultra-low cryogenic temperatures to temperature reaching 1000 °C, and from the vacuum of space to 1000 bar, there’s a solution available!
