VM 92 VUV Monochromator and Spectrometer


 


  • High throughput f/2.2
  • Spectral range from 25 nm to 600 nm
  • Single concave holographic grating for high VUV efficiency
  • Can be easily switched from a monochromator to CCD-based spectrometer
  • Readily purged with Nitrogen or Helium for easy VUV
  • Can be pumped through entrance slit
  • Only 2 kg. mass 0.5 liter internal volume
  • Back-Thinned CCD camera options
  • Fixed interchangeable or adjustable slits
  • Manual with wavelength dial or add-on stepper motor drive with PC-based controller and Labview-based SW
  • Labview drivers and code for integration into user SW


The Resonance Ltd vacuum monochromator and spectrometer packs great performance in a small package. The compact 2 kg system can be coupled directly to a vacuum chamber through a 2.75" Conflat® style flange to observe processes in a vacuum system.  The f/2.2 grating is a type 4  for minimal  abberations.

The system can be configured either as a manual monochromator, a motorized monochromator or as a CCD spectrometer using interchangeable accessories.
