VUV/UV Monochromator/Spectrometer

The Resonance Ltd vacuum monochromator and spectrometer packs great performance in a small package. The compact 4 kg system can be coupled directly to a vacuum chamber through a 2.75" Conflat┬« style flange to observe processes in a vacuum system.  Its single grating design provides high VUV efficiency while the 300 mm focal length offers an excellent balance between size and functionality.  The system can be configured either as a manual scanning monochromator, a motorized scanning monochromator or as a CCD spectrometer using interchangeable accessories.
