| G395M/F290LP | 2.9–5.2 | 730–1315 |
| GI40H/F070LP | 0.7–1.3 | I320–2395 |
| GI40H/FI00LP | 1.0–1.9 | 1850–3675 |
| G235H/FI70LP | 1.7–3.2 | 1910–3690 |
| G395H/F290LP | 2.9–5.2 | 1930–3615 |
Notes. For the grating-based configurations, the quoted wavelength ranges refer to spectral regions free from overlap with any significant second order emission exceeding the 0.1% level. In the MOS mode, spectra from the high-resolution gratings (italicised, grating names suffixed with H) may suffer significant wavelength cut-off at the red end.
