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.
