• Spectrograph and monochromator functions
• Gratings with optimal efficiency
• Wavelength range of 80–300 nm
• High-precision wavelength setting
• Compact, modular design

The easyLIGHT VUV is a compact VUV spectrometer with a highly competitive price. Its spectral range covers 80–300 nm. Aberration-corrected gratings provide best-in-class efficiency of up to 43%. The combined spectrograph and monochromator functionality offers maximum flexibility. The entrance and/or exit slits can be adjusted continuously, either manually or motorized.

Available detector types:

• VUV CCD cameras offer the highest resolution and dynamic range
• MCP and CMOS detectors provide the widest wavelength coverage, as well as gating and intensified detector capabilities
• Photomultiplier tubes are suitable for scanning applications

Custom designs based on the easyLIGHT spectrometer can be discussed.

Modular design

The versatile and flexible design of the easyLIGHT allows for rapid switching between spectrograph and monochromator modes. The entrance and detector/exit ports are interchangeable. Three auxiliary ports are available for installing vacuum pumps, vacuum gauges, additional feedthroughs, and more.

The figure above illustrates the detection of sulfur in a lunar analog sample using laser-induced breakdown spectroscopy (LIBS). The aim was to investigate the potential of VUV-LIBS for Mars missions. The results indicate improved sulfur detection capability compared to LIBS in the standard spectral range. The detection limit for sulfur was estimated to be 0.5 at%.
