Preposition: on

• telescope: At UNSW I started the " Fornax Cluster Spectroscopic Survey " using the 2dF spectrograph on the Anglo-Australian Telescope.

Modifies a noun

• slit: The IFUs dissect the field into individual elements, which are then re-arranged to form part of the spectrograph entrance slit.

• module: Spectrograph Module The spectrograph module contains a number of individual spectrograph units.

• unit: Spectrograph Module The spectrograph module contains a number of individual spectrograph units.

• design: The basic spectrograph design is shown in figure 1. The spectrograph system contains only one moving part: the camera shutter.

Adjective modifier

• 2df: There is also a web page showing pictures of the 2dF spectrograph.

• infrared: Small Dark Spot This image was obtained when the infrared spectrograph was mapping Neptune.

• integral: It is a wide field optical integral field spectrograph aimed at performing deep field science.

• optical: It is a wide field optical integral field spectrograph aimed at performing deep field science.

• multi-object: This is why astronomers are developping multi-field spectroscopy where integral field units replace the lenses or slits in a multi-object spectrograph.
