Fiber Optic Interface for UHV or High Vacuum Systems

Creating an easy way to use optical fibers with vacuum systems and pressure chambers, Fiberguide Industries' offers its Fiber Optic Feedthroughs. The feedthroughs can be used for any medical, industrial or research application that requires optical interfacing with UHV or high vacuum systems.

Fiberguide Industries' feedthrough line provides inlet and outlet tubes through the walls of pressurized or vacuum systems by using a hermetic seal, all while maintaining the integrity of the vacuum.

Fiber optic feedthroughs are available in cell, flange and port designs. They are perfect for a wide range of wavelengths and operating temperatures up to 175ºC (250ºC for pigtail), utilizing Fiberguide's gold coated fiber.

Fiber selection includes Multimode, Single Mode and Polarization Maintaining (PM), with core diameters from 50µ to 1500µ and connector interface selections of SMA (standard), ST, FC or ferrule style. All fibers are helium leak-tested and certified to 10-7 torr. Industry standard mounting flanges and custom configurations for the housing are available, and custom lengths and designs can be provided for the shaft. Standard mounting configurations include threaded mount feedthroughs, nut mount feedthroughs and Con-Flat / ISO flange mount feedthroughs.
