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.

XUV spectrum of HHG from a fiber laser system, measured with HP Spectroscopy highLIGHT XUV

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.

XUV spectrum of HH19 generated with two time-delayed pulses, measured with HP Spectroscopy highLIGHT XUV

Spectra of highLIGHT XUV of the 19th harmonic of a 1030nm driver laser tuned by changing the delay of the driving pulse pair over a delay range of more than one driving laser cycle. White crosses represent the central photon energy of the driving composite pulse multiplied with the harmonic order 19.

spectrum of line emission of nitrogen at 2.88nm, measured with HP Spectroscopy highLIGHT SXR+

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.
