high-resolution XUV spectrometer highLIGHT


high-resolution spectrometer

  • flat-field grazing-incidence spectrometer

  • best-in-class spectral resolution

  • wavelength range from 1 to 100 nm

  • high-efficiency no-slit mode

highLIGHT offers the highest spectral resolution in convenient flat-field configuration on the market. Resolution of 0.006nm or better combined with wide single-shot wavelength coverage. highLIGHT can be used with or without entrance slit.

Its modular design features an integrated slit holder and filter insertion unit, as well as a motorized grating positioning.

Detector options include both XUV CCDs for highest resolution and dynamic range, and MCP/CMOS detectors for broadest wavelength coverage and gated / intensified detection. Please contact us to discuss your needs.

Customized derivatives of our highLIGHT spectrometer are also available.

No-slit design

The proprietary spectrometer design by HP spectroscopy uses direct source imaging. Consequently, a narrow entrance slit is not needed and light collection is maximized. Comparing with traditional spectrometer architectures, a factor of 20 more light reaches the spectrometer detector. The architecture also greatly increases day-to-day operation robustness.

Spectrum of the 9th and the 11th harmonic of a frequency-doubled Yb-doped fiber laser system (334kHz, 90uJ, <300fs) measured with highLIGHT XUV. The spectral bandwidth of the harmonics is ∼20 meV FWHM, which corresponds to a relative energy bandwidth of ΔE/E = 7.5E-4.

Emission spectroscopy measurement of nitrogen line at 2.88nm (430eV, transition 1s2-1s2p) with highLIGHT SXR+. The FWHM is 1.7 pixels of the CCD camera (13um pixel size), resulting in a resolving power of 1890. The detector-limited resolving power is 3290.
