Ruggedized multichannel hermetic fiber-optic feedthroughs
The KTRAV-T12 ruggedized multichannel hermetic fiber-optic feedthroughs are designed for high & ultra-high vacuum applications. They feature extremely low outgassing rates and helium leak rates.
Every feedthrough channel is built with an internal fiber rod identical to the fiber used upstream and downstream for perfect matching of the optical characteristics of each line.
These ruggedized multichannel hermetic fiber-optic feedthroughs can be made with polarization maintaining [PM] fibers as well as with any singlemode [SM] fibers. They can also come with multimode [MM] graded-index [GI] fibers or step-index [SI] fibers with a cladding diameter of 125 μm. We offer these configurations with either FC/APC or FC/PC connectors. The KTRAV-T12 feedthroughs are also available with SMA connectors and are suitable for large core fibers from 100 µm to 400 µm, Low OH, High OH, and solarization resistant fibers.
Standard configurations are available with 1 to 3 individual channels within one DN 40 KF flange or up to 4 channels within a DN 40 CF flange. Custom designs are also possible upon request; we offer different sizes of ISO, CF and KF flanges.
