Description
Flangeless Vacuum Fiber Optic Feedthroughs
Versatile Solutions for Laser Welding and O-Ring Sealing
Our flangeless vacuum feedthroughs offer ultimate flexibility for UHV (Ultra-High Vacuum), XHV (Extreme High Vacuum), and Cryogenic applications. These modular components are designed to be integrated directly into your existing hardware, supporting a wide range of fiber types including Single-Mode (SM), Multi-Mode (MM), and Polarization-Maintaining (PM) fibers.
Integration Options: Weldable vs. O-Ring
We provide two distinct mounting styles to suit your specific chamber requirements:
1. Weldable Fiber Feedthroughs
Designed for permanent, high-integrity integration. These are ideal for extreme vacuum environments and ultra-low temperatures.
-
Direct Integration: Engineered for laser welding into CF, KF, or ISO-K flanges.
-
Maintainability: Features a replaceable internal zirconia sleeve, ensuring long-term utility even if the internal alignment is damaged.
2. O-Ring Sealed Feedthroughs
The perfect choice for systems requiring frequent maintenance or rapid prototyping.
-
Easy Installation: Can be installed or replaced in minutes without specialised welding equipment.
-
Serviceable Design: These units can be returned for professional connector repolishing. Like our weldable versions, the internal zirconia sleeve is fully replaceable.
Technical Advantages
-
Superior Sealing: Helium leak rates guaranteed from 10-10 to 10-12 mbar·l/s.
-
Full UHV Compatibility: Materials and construction methods optimised for zero outgassing.
-
Universal Connectivity: Fully compatible with FC, SMA 905, and ST connectors.
-
Flexible Mounting: Available as standalone components or pre-mounted on standard flanges.
