Abstract
In this paper we report on the preliminary design of DAVINCI, the first light science instrument for the W. M. Keck Observatory's Next Generation Adaptive Optics facility. DAVINCI will provide imaging and coronagraphy at the diffraction limit from 0.7 μm to 2.4 μm over a field of ~30", and integral field spectroscopy with three sampling scales (10, 35, and 50 mas) and a field of view of 5.6" x 3" for the largest (50 mas) sampling scale. The science requirements for DAVINCI are discussed, followed by an examination of the challenges of designing the instrument within a strict limit on overall cost. The instrument's optical design and opto-mechanical configuration is described as well as the current performance predictions for the instrument.
