I describe a new high-contrast imaging effort involving an integral field spectrograph and coronagraph recently installed behind the adaptive optics system at the Hale 200-inch telescope at Palomar. This package, called "Project 1640" serves as the basis of a long-term observational program in high-contrast imaging at Palomar. Our J and H band spectrograph will aid in speckle suppression and aims to give us low resolution spectra of brown dwarfs and exoplanets. This system has similar science goals as a new generation of apodized pupil coronagraphs combined with high-order adaptive optics and integral field spectrographs (e.g. GPI and SPHERE). I will describe the project, and show some recent data. This work was performed [in part] under contract with the California Institute of Technology (Caltech) funded by NASA through the Sagan Fellowship Program.
