Diamond Vacuum Windows

Diamond vacuum windows are embedded in UHV conflat vacuum flanges using a hermetic diamond-metal joint optimized for low thermo-mechanical stress and a wide range of operation temperatures.

Their exceptional spectral transparency covering the visible, infrared, terahertz and microwave region make them an ideal choice for multi-spectral applications including synchrotron beam lines and space based spectroscopic systems.
