FIDEOS is the second high resolution spectrograph developed at the AIUC after the successful experience of PUCHEROS (include link to Pucheros). The concept instrument is the same, basically a relatively high resolution spectrograph for the optical spectral range providing relatively high stability for radial velocity measurement.
The characteristics of the instrument are:
| Spectral range | 400 – 750 nm |
| Spectral Resolution | 40,000 |
| Aperture on sky | 1.9 arcsec diameter |
| Telescope | ESO 1m, La Silla |
| Calibration | Symultaneous ThAr or Iodine |
| Detector | FLI PL 230 |
The optical design is a classic echelle based on a R2.7 grating, cross dispersion is provided by two prisms.
The instrument is thermally stabilized and mounted on anti-vibration supports to provide high stability. Wavelength calibration is provided by simultaneous spectrum of a ThAr lamp.
