Vacuum UV Spectroscopy

VUV Accessories

Based on modular designs, our VUV monochromators can be coupled with several accessories.

Source: Deuterium Lamp

The DLS200 is a 200W Deuterium lamp equipped with a MgF2 window to allow vacuum UV radiation down to 115 nm. This lamp is coupled with a mirror chamber to focus the beam on the entrance slit of a monochromator.

Detection

: PMT in housing

: CCD detector

HORIBA Scientific can provide VUV detection solutions for your setup. Single or multichannel detectors are available, along with data acquisition modules compatible with our software. When delivered with our monochromator or spectrograph, we ensure the mounting, testing, calibration of the complete system and guarantee the vacuum level.
