Infrared (IR) nanospectroscopy is a non-destructive method for the analysis of molecular structures below the wavelength scale. It is used in a broad range of research applications spanning from biochemistry to geology. A magnetic bearing chopper is a core component to bring this IR method to the next level of spatial resolution. It provides the beam chopping functionality in vacuum, at high frequency and with very low jitter.

Fuel cell technology is continuously gaining ground in E-mobility applications. Fuel cells require a constant supply of pressurized air, for which high-speed turbo compressors with air bearings are an optimal choice to reduce size, guarantee oil-free operation required for the lifetime of the fuel cell, and increase efficiency.

Turbo compressors have to cope with the vibration and lifetime requirements when used in mobile fuel cell applications, such as road vehicles. For ball-bearing compressors, vibration levels impact bearing wear and, therefore, the lifetime. However, this is different for gas bearing compressors, such as the CT-2X compressors: The vibration levels define whether there is any influence on the gas bearing compressor lifetime, if any at all. For this reason, it is necessary to validate the compressor on a test rig in order to verify the specified vibration requirements and to prove the functionality and lifetime impact.
