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|
|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.
