Ocean Optics offers a full line of fiber vacuum feedthrough accessories for vacuum chamber applications such as semiconductor and thin film processing. These vacuum feedthroughs include general-purpose bolt-style feedthroughs with an O-ring, and feedthroughs mounted in conflat and ISO KF industrial-grade flanges. All have in-vacuum and in-air side male SMA 905 connectors for coupling to optical fibers (available separately).
O-ring bolt-style feedthroughs are designed to perform well in NEMA enclosures, glove boxes and moderate- to high-pressure applications, while conflat and ISO KF flanges are ideal for mounting to an existing vacuum chamber port.
- Each feedthrough comes with two splice bushings, which are in-line adapters to mate SMA 905 connectors
- O-ring feedthroughs can be screwed into a 3/8-24 external threaded hole in the vacuum chamber, or can be bolted into a smooth hole with the provided nut and washer
- Metal-jacketed optical fiber assemblies are recommended for the low-pressure side of the chamber to minimize outgassing
