CIRPASS: The Cambridge Infrared PAnoramic Survey Spectrograph |
First light (at ING): 26 December 2003. Designed and built by: Institute of Astronomy, University of Cambridge.
Description: CIRPASS is a near-infrared (0.9 - 1.8 microns) fibre-fed spectrograph. Two fibre feeds exist: a 490 element integral field unit (IFU) and a 150 fibre multi-object bundle. The large spectrograph is operated inside a freezer working at -40 degrees celsius. The spectrograph camera, the filters and the detector are inside a dewar which is cooled by liquid nitrogen. The optics deliver a high resolution (R>3000) spectrum on to a mirror surface which is then reimaged on to the detector. This provides the option to block out, or suppress, the bright OH emission by making the mirror (or mask) non-reflective at the positions of the OH lines.
