Vacuum UV Spectroscopy
Vacuum UV - Toroidal Grating Spectrograph (TGS)
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°.
