VM200 VUV Monchromator and Spectrometer
The Resonance Ltd. vacuum monochromator and  spectrometer uses standard connections to allow  simple integration into most systems. The f/4.2 grating  is a type 4 for minimal aberrations. It is designed to  allow easy interchangeability between being a  monochromator with servo-controlled drive and a  CCD-based spectrometer. It’s supplied with LabView-  based codes and drivers for integration into user  software. 
The VM200 packs  performance in a small  package. The compact 2.5-kg  system can be coupled directly  to a vacuum chamber through  a 2.75” Conflat™ style flange.   Its single-grating design  provides high VUV efficiency  while the 200mm focal length  offers an excellent balance  between size and functionality. The system can be configured  as a manual monochromator, a  motorized monochromator or  as a CCD spectrometer using  interchangeable accessories.
