The KTRAV-M8V hermetic fiber-optic feedthrough is a compact single-channel feedthrough in M8- thread screw-in SMA adapter interface.
It is suitable for high vacuum applications and ensures a high level of hermeticity of 10-8 mbar.l/s.
It accepts multimode step-index fibers with 200 μm to 1500 μm core diameter, with a numerical aperture of 0.22 (silica/silica) or 0.37 (silica/polymer).
The M8V version exists with SMA connectors.
The KTRAV-M8V is a solution suitable for a panel thickness of 6 to 15 mm with a hole diameter of 8 mm.
