Description Of CF Flange Beryllium Window

CF Flange Beryllium Window is a precision-engineered window assembly designed for ultra-high vacuum (UHV) applications. It consists of a high-purity beryllium foil diffusion bonded to a CF (ConFlat) flange, providing a reliable vacuum seal while allowing high X-ray transmissivity. Beryllium is a lightweight, silver-grey metal with a density of 1.848 g/cm³, excellent X-ray transmissivity, and superior mechanical strength.

The diffusion bonding process creates a metallurgical bond between the beryllium foil and the flange, eliminating the need for adhesives or gaskets that could outgas or fail in UHV conditions. This construction ensures reliable vacuum tightness with leak rates below 3×10⁻¹⁰ mbar·L/s, making it ideal for synchrotron beamlines, X-ray detectors, and semiconductor inspection equipment.

CF flange beryllium windows are available in standard CF flange sizes (CF35, CF63, CF100, etc.) and custom configurations. Beryllium foil thickness from 8μm is available, with purity grades including IF-5 (99.5%) and PF-60 (99.0%). All windows are cleaned and packaged for UHV service, with full material certification and leak testing.
