easyLIGHT VUV spectrometer


compact VUV spectrometer

  • spectrograph and monochromator functionality

  • grating with best-in-class efficiency

  • wavelength range from 80 to 300 nm

  • high accuracy wavelength setting

  • compact and modular design

easyLIGHT VUV is an intuitive and compact spectrograph for the VUV spectral range with competitive pricing. Spectral coverage extends from 80nm to 300nm. The aberration-corrected grating provides best-in-class efficiency of up to 43%.

The combined spectrograph and monochromator functionality gives highest flexibility. Entrance and/or exit slits are continuously adjustable manually or motorized.

Detector options include

  • VUV CCDs for highest resolution and dynamic range

  • MCP/CMOS detectors for broadest wavelength coverage and gated / intensified detection

  • photomultiplier detectors for scanning applications

Please contact us to discuss your needs.

Customized derivatives of the easyLIGHT spectrometer are also available.

Modular design

application note


VUV spectrum from LIBS on lunar-analog samples

Sulfur detection by Laser Induced Breakdown Spectroscopy (LIBS) on lunar-analog samples. The aim is to study the potential of VUV-LIBS on a mission to Mars. The results indicate improved detection capabilities for sulfur as compared to LIBS in standard spectral ranges. Limits of detection for S are estimated at 0.5at%.

VUV spectrum of high harmonic radiation reflected from monocrystalline silicon

Experimental high harmonic spectra reflected from monocrystalline silicon with linear polarization of the driving pulse along [100] (black curves) and [110] (red curves) crystallographic directions. The central photon energies of the driving pulses are 0.6 eV (wavelength of 2000 nm).
