320 mm imaging spectrometer corrected for aberrations across the full focal plane, for multichannel spectroscopy.

HiperS-320i is a 320 mm imaging monochromator/spectrograph that applies full-focal-plane imaging correction to suppress astigmatism across the whole focal plane. An on-axis rotating grating turret and automatic focusing keep resolution and image quality consistent when gratings are changed, so intensity values are reliable over the full CCD. It is suited to LIBS, Raman, fluorescence and other molecular spectroscopy, including multichannel fiber-bundle measurements.

Key Features

  • Full-focal-plane aberration correction for sharper peak shapes, more precise wavelengths and higher spatial resolution
  • On-axis grating rotation increases grating utilization by 15% and keeps grating efficiency consistent
  • Automatic focusing moves to the optimum focal plane whenever the grating is switched
  • Built-in resolution enhancement module improves spectral resolution by up to about 20%
  • Optional two entrance and two exit ports with automatic switching
  • Multichannel imaging, demonstrated with a 9-core, 100 µm fiber bundle over a 3.8 mm image height
  • Triple turret for up to three 68 × 68 mm gratings, from 150 to 2400 g/mm

Typical Applications

  • Laser-induced breakdown spectroscopy (LIBS)
  • Raman spectroscopy
  • Fluorescence and photoluminescence
  • Molecular spectroscopy
  • Multichannel fiber-bundle spectroscopy
