Product Overview: Precision Viewing in Ultra-High Vacuum
The KINTEK CF Ultra-High Vacuum Observation Window Flange, featuring a high borosilicate glass sight glass, is meticulously engineered for demanding environments requiring ultra-high vacuum conditions (typically above 10-9 Torr). It provides a reliable and clear viewing port essential for monitoring and controlling processes in high-end scientific research and advanced industrial applications. Leveraging our R&D expertise and in-house manufacturing, we offer both standard and deeply customized solutions to meet your specific experimental needs.
Key Features
High Borosilicate Glass Sight Glass
- Exceptional Thermal Stability: Operates effectively across a wide temperature range (-200°C to +300°C) with a very low thermal expansion coefficient (3.3 x 10-6/K), minimizing distortion and maintaining integrity under thermal stress.
- Superior Chemical Resistance: Highly resistant to acid and alkali corrosion, ensuring durability and a long service life even in reactive environments.
- Optimal Optical Clarity: Delivers over 92% light transmittance for clear, unobstructed observation of processes within the vacuum chamber.
Robust Stainless Steel Flange
- UHV Compatibility & Durability: Constructed from high-quality stainless steel (typically 304L or 316L) for high strength, excellent corrosion resistance, and suitability for ultra-high vacuum applications.
- Reliable Sealing Performance: Precision engineered with CF knife-edge design to ensure a robust and leak-tight seal when used with an appropriate gasket, critical for maintaining stable ultra-high vacuum environments.
Designed for Versatility and Integration
- Broad Range of Specifications: Available in multiple CF flange sizes (from CF16 to CF200 and beyond) and various high borosilicate glass dimensions to suit diverse equipment and experimental setups.
- CF Standard Compliance: Ensures easy installation, interchangeability with other CF components, and straightforward maintenance, saving valuable time and effort.
Advantages for Your Critical Applications
- Unwavering Reliability in UHV: The synergistic design of high-quality borosilicate glass and stainless steel ensures consistent, stable operation, crucial for sensitive ultra-high vacuum processes.
- Enhanced Process Monitoring: Achieve precise control and detailed observation thanks to the exceptional clarity, stability, and minimal outgassing of the viewing window.
- Adaptable to Your Unique Requirements: Beyond our standard offerings, KINTEK’s strong deep customization capability allows us to tailor flanges to your specific dimensions, alternative glass materials (e.g., sapphire, quartz), anti-reflective coatings, or other unique requirements. Discuss your custom project with our experts.
- Long-Term Value: Durable materials, robust construction, and careful manufacturing lead to a prolonged service life and reduced maintenance, offering an excellent return on investment for your critical UHV systems.
Typical Applications
This CF observation window flange with high borosilicate glass is indispensable for a variety of UHV and HV applications, including:
- Semiconductor Manufacturing: Critical for in-situ observation during wafer processing, PVD, CVD, and etching.
- Vacuum Coating Systems: Essential for real-time monitoring of thin-film deposition processes and coating quality.
- Optical Instruments & Laser Systems: Provides clear optical access for internal components and beam paths in vacuum.
- Aerospace & Space Simulation Chambers: Supports research and testing in environments mimicking the vacuum of space.
- Advanced Scientific Research: Facilitates detailed observation in surface science (e.g., XPS, AES, LEED), particle accelerators, fusion research, and materials science experiments.
- Industrial Vacuum Processes: Used in vacuum furnaces, electron beam welding, and other high-vacuum industrial equipment requiring visual monitoring.
Working Principle
The CF ultra-high vacuum observation window flange operates by creating a hermetically sealed viewing port into a vacuum chamber. The high borosilicate glass serves as the transparent barrier, selected for its excellent optical properties, thermal stability (low expansion coefficient), and chemical resistance. The stainless steel CF flange utilizes a knife-edge sealing principle: when bolted to a mating CF flange with a soft metal gasket (typically oxygen-free copper) in between, the knife edges indent the gasket, creating an extremely reliable metal-to-metal seal capable of maintaining ultra-high vacuum conditions. This robust design allows for direct visual or instrumental observation of internal processes without compromising the integrity of the vacuum environment.
