Port Aligners for Ultra-High Vacuum (UHV) Systems
Port aligners are precision-engineered components designed to adjust the distance and angular relationship between two flanges in ultra-high vacuum (UHV) systems. These tools are essential for aligning vacuum components where exact positioning is crucial. In particular, they are used for the final alignment of sample transfer arms and other critical UHV instruments. The port aligner works by allowing a fixed flange to support three equally spaced threaded shafts, while a travelling flange has adjustable floating mounts to accommodate precise movement. This allows for controlled and secure adjustments during the installation and alignment of UHV systems.
Ideal for use in scientific research, semiconductor manufacturing, and vacuum chamber assembly, port aligners ensure that UHV components are correctly positioned, reducing the risk of vacuum leaks and improving the overall integrity of the vacuum system. The versatility of these aligners means they are compatible with various types of UHV equipment, ensuring optimal performance across different applications.
Key Applications:
- Precision alignment of vacuum flanges and sample transfer arms in UHV systems
- Final alignment adjustments in vacuum chamber assembly and beamline experiments
- Suitable for use in scientific research laboratories, semiconductor fabrication, and vacuum system production environments
Customisation Options:
The port aligners from UHV Design offer customisation to meet the specific requirements of diverse UHV systems. Adjustable features allow for precise control of axial and angular alignment, providing enhanced flexibility in positioning vacuum components. Built with durable 316L stainless steel bellows, these port aligners are designed to handle the stresses of vacuum environments while maintaining full UHV compatibility. With a wide range of configurations, UHV port aligners deliver dependable performance for applications requiring precise alignment and secure flange connections.
