Summary

ISAAC is an IR (1 - 5 μm) imager and spectrograph that lies at the Nasmyth A focus of UT3. It has two arms, one equipped with a 1024 x 1024 Hawaii Rockwell array, and the other with a 1024 x1024 InSb Aladdin array from Santa Barbara Research Center. The Hawaiiarm is used at short wavelengths (1 - 2.5 μm). Prior to P70, theAladdin arm was used exclusively at long wavelengths (3- 5 μm). From P70 onwards this arm is also offered for JHK imaging.

Publications based on data obtained with the ISAAC instrument should quote the following reference paper: Moorwood, A. et al. 1998, The Messenger 94, 7.
