The FMOS-Echidna instrument:
- has 400 science spines and 14 guide spines covering a 0.5° field-of-view.
- positions each spine within 10 microns of its target position.
- can configure a field (position all spines) in < 10 minutes.
- observes in near-IR wavelengths (0.8 - 1.9 micron).
- has a plate scale of ~83 microns/arcsecond.
- Utilises a 3-element corrector to convert the ~f/1.8 beam to ~f/2.1.
- has an allocation efficiency of ~88%. (for 400 randomly distributed objects)
- uses a 100 micron (core) diameter optical fibre in each science spine.
- uses 7 50 micron (core) diameter optical fibres in each guide spine.
