Detail & Parts

Working Principle

The KF ultra-high vacuum observation window operates by integrating high borosilicate glass with a 304 stainless steel flange. The glass provides a clear view into the vacuum chamber, while the flange ensures a robust and sealed connection. This combination allows for continuous observation and monitoring of processes within the ultra-high vacuum environment without compromising the integrity of the vacuum.

Key Components

• High Borosilicate Glass: Acts as the observation medium, transmitting light with minimal distortion and resisting thermal and chemical stresses.
• Stainless Steel Flange: Serves as the structural and sealing element, maintaining the vacuum integrity and supporting the glass securely.

Functionality

• Observation: The high borosilicate glass allows for clear observation of the vacuum chamber's interior, crucial for monitoring and control.
• Sealing: The stainless steel flange ensures a tight seal, preventing any air leakage and maintaining the ultra-high vacuum environment.
• Durability: Both materials are chosen for their durability and resistance to the harsh conditions of ultra-high vacuum environments.
