Summary

SINFONI is a near-infrared (1.1 -- 2.45 µm) integral field spectrograph fed by an adaptive optics module, currently installed at the Cassegrain focus of UT3. The spectrograph operates with 4 gratings (J, H, K, H+K), providing a spectral resolution around 2000, 3000, 4000 in J, H & K respectively, and 1500 in H+K -- each wavelength band fitting fully on the 2048 pixels of the Hawaii 2RG (2kx2k) detector in the dispersion direction. The spatial "pixel" scale is selectable from 0.25", 0.1" to 0.025" per image slice, corresponding to field-of-views of 8"x8", 3"x3" and 0.8"x0.8" respectively. The instrument can be used with a Natural Guide Star or a Laser Guide Star to provide near diffraction-limited observations. It can also be used for seeing-limited open-loop observations.

Publications based on data obtained with the SINFONI instrument should quote the following reference papers: Eisenhauer, F. et al. 2003, SPIE 4841, 1548 and Bonnet, H. et al. 2004, The ESO Messenger 117, 17.
