Scientific paper

We are proposing to build a new integral field instrument (OSIRIS) for use with the Keck Adaptive Optics System. It will utilize a large (1024 element) fiber optic bundle to slice the field and feed a standard infrared spectrograph with a spectral resolution of 5000. To improve the fill factor of the fiber bundle, we plan on coupling it to a matched lenslet array. The spectrograph will have three plate scales of 0.05'', 0.10'' and 0.20'' per pixel, and full broad band spectra will fit on a single 2048x2048 infrared array. Other innovations include using some of the fibers for pseudo-slits and sky measurements and non-uniform spacing for the "linear" feed to the spectrograph.
