We describe Cornell's near-infrared camera system PHARO (Palomar High Angular Resolution Observer) built for use with the JPL Palomar Adaptive Optics System on the 5 m Hale telescope. PHARO uses a 1024x1024 HgCdTe HAWAII detector for observations between 1 and 2.5 µm wavelength. An all-reflecting optical system provides diffraction-limited images at two scales, 25 and 40 mas.pixel^–1, plus a pupil imaging mode. PHARO also has a coronagraphic imaging capability and a long-slit grism spectroscopy mode at resolving power ~1500. The instrument has been in use with the AO system at Palomar since early 1998.
