High-speed magnetic bearing chopper for infrared nanospectroscopy
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.
