First light (at ING): 1994
Designed and built by: Instituto de Astrofisica de Canarias.
Description: The 2D-FIS system is a bundle of 125 optical fibres distributed in the focal plane of the telescope in a central rectangle, covering an area of about 9.2 arcseconds × 12.2 arcseconds on the sky, and an outer ring of fibres at 38.4 arcseconds from the center, to measure the sky background light. The 95 inner fibres have a core diameter of 0.9 arcseconds. These fibres are then fed into the slit of the ISIS double-beam spectrograph, so that the gratings, filters and dichroics of ISIS can be used.
