Vacuum UV - Toroidal Grating Spectrograph (TGS)

TGS Optical Layout

TGS Optical Layout
  • High luminosity : only one optical piece (aberration corrected toroidal holographic grating).
  • Medium resolution.
  • Grating fixed position.
  • Flat focal field to accomodate multichannel detector.
  • Spectral range : from 170 nm to 10 nm.
  • Exit arm length : 685 or 306 mm.
  • Deviation angle : 140°.
