Description Of Beryllium Dome Window
Beryllium Dome Window is a high-purity beryllium metal window in a hemispherical dome shape, specifically designed for X-ray and vacuum applications. Beryllium is a lightweight, silver-grey metal with a density of 1.848 g/cm³, excellent X-ray transmissivity, and superior mechanical strength. The dome shape with flange allows for direct mounting into vacuum chambers and X-ray detector systems.
Beryllium offers a unique combination of properties that make it ideal for X-ray window applications. With low density and low atomic number (Z=4), beryllium provides high transmissivity for low-energy X-rays, minimizing spectral contamination and improving detection sensitivity. The material also offers high strength even in thin sections, excellent vacuum tightness, and good thermal stability. The dome geometry provides additional structural rigidity and allows for a larger viewing area compared to flat windows.
High purity beryllium dome windows are available in custom sizes and flange configurations, with surface finishes including machined, polished, and vacuum-tight. Typical applications include X-ray detectors (EDXRF, WDXRF, XRD), synchrotron beamlines, medical imaging systems, and vacuum systems.
