19 Facility Infrared Instrumentation Summary Expect any major facility (with a few exceptions) to have Imaging camera Multi-mode: wide-field vs. adaptive optics Extensive filter set (Y,J,H,K, +narrowband and continuum) Coronagraphic mode (or separate coronagraphic instrument) Grism for utility spectroscopy Maybe a Fabry-Perot for narrow-band scanned imaging Spectrograph Multi-object and/or Cross-dispersed Multi-grating/resolution Echelle usually requires separate instrument due to grating/optics size Integral field (deployable) Wavelength coverage 1-2.5um HgCdTe; 1-5um InSb; 7-26um Si:As
