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


Absorption spectra of two-photon transitions in xenon, driven non-degenerately with VUV light and an auxiliary light field, and recorded by easyLIGHT VUV with an intensified CCD camera. (b) Different wavelengths of the auxiliary light field (480-510nm) result in spectrally shifted spectra. (c) The wavenumber sum of the two driving light fields.

VUV spectrum of tunable frequency comb based on cavity-enhanced harmonic generation, measured with easyLIGHT VUV

Laser spectroscopy of the nuclear clock transition in Thorium at approx. 150nm paves the way for the future construction of a nuclear-based optical clock. A tunable precision laser source based on cavity-enhanced seventh-harmonic generation is characterized by easyLIGHT VUV.

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 measured with easyLIGHT VUV. The central photon energies of the driving pulses are 0.6 eV (wavelength of 2000 nm).

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 with easyLIGHT indicate improved detection capabilities for sulfur as compared to LIBS in standard spectral ranges. Limits of detection for S are estimated at 0.5at%.
