In fields such as semiconductor manufacturing, high-energy physics experiments, and aerospace ground simulation, the purity of the vacuum environment is the lifeline for the success of experiments and processes. When introducing or extracting optical signals into or out of a Vacuum Chamber, the most critical challenge lies in ensuring that the connection component does not become a source of leaks or a source of contamination (outgassing).
[Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS)] offers the OFSCN® Fiber Optic Vacuum Sealed Flange, a feedthrough solution specifically designed for high-reliability, Ultra-High Vacuum (UHV) environments.
This article will analyze how our core technology ensures your UHV system meets the highest standards of "Zero Leak, Zero Outgassing."
I. Core Challenge One: Hermeticity and the Ultimate UHV Standard
Standard connectors cannot be used in vacuum environments because their rubber gaskets or polymer materials contain microscopic leak paths and cannot withstand extremely low pressures.
- OFSCN® Solution:
- Vacuum Level Guarantee: Our flange employs precision welding and special encapsulation processes to ensure sealing in Ultra-High Vacuum environments. The standard product guarantees a vacuum level better than 1*10-5 Pa, and higher UHV levels can be customized based on customer requirements.
- Standardized Interface: The flange is available in the industry-standard KF (clamped) and CF (knife-edge) series, such as CF35 and KF25, ensuring complete compatibility and reliable connection with existing vacuum systems.
II. Core Challenge Two: The Threat of Contamination and Outgassing
In a UHV environment, even trace amounts of gas release (outgassing) can severely contaminate the chamber, compromising experimental results or the quality of semiconductor films. Traditional non-metallic sealing materials and adhesives are major sources of outgassing.
- OFSCN® Solution:
- Material Selection: The main body of our flange utilizes stainless steel and other UHV-compatible materials. The internal sealing components are made of special ceramics and glass materials that have undergone vacuum compatibility treatment, ensuring that the outgassing rate remains extremely low even after long-term pumping and high-temperature baking.
- High-Temperature Bakeout Capability: UHV systems typically require baking to remove adsorbed gases and moisture from material surfaces. The OFSCN® flange is designed to withstand high bakeout temperatures (standard product is 50°C, higher can be customized), accelerating the outgassing process and allowing the required UHV level to be achieved faster.
III. Key Value: Connector Stability and Compatibility
In addition to sealing performance, the flange must also ensure the stable transmission of the optical signal.
- High-Compatibility Connectors: The flange supports various standard fiber optic connector types, including FC/APC—critical for high return loss requirements—as well as common types like FC/PC, ST/PC, and SMA905.
- Low Insertion Loss: The flange has minimal impact on the optical signal quality during feedthrough, ensuring low insertion loss and maintaining the accuracy of data acquisition and transmission.
- Multi-Channel Customization: For complex experimental needs, we can provide multi-channel designs according to customer requirements, allowing multiple fibers to be introduced or extracted through a single flange, simplifying system integration and routing.
Summary: High-Reliability Connectivity for the Future
Whether used to introduce FBG sensors into a space environment simulation chamber or as a precise optical interface for semiconductor sputtering equipment, the OFSCN® Fiber Optic Vacuum Sealed Flange provides the most technologically reliable solution. It eliminates the risks of leakage and outgassing, ensuring your scientific research and industrial processes flow smoothly at UHV extremes.
