Products for Spectroscopy

For Spectroscopy we provide Radio Frequency Pulse Power Amplifiers – narrowband for Hydrogene and broadband for X-Core detection – , highly stable Current Sources – e.g. Shim Power Supplies and Low Noise Amplifiers. They have been applied successfully in

  • Magnetic Resonance Imaging MRI
  • Nuclear Magnetic Resonance NMR
  • Electron Spin Resonance ESR
  • Electron Nuclear Double Resonance ENDOR

RF Pulse Power Amplifiers

All Radio Frequency Pulse Power Amplifier series employ state of the art semiconductor technology.
