摘要：

We describe the design, characterisation and performance of the Infrared Camera for Adaptive Optics at Lick (IRCAL), IRCAL is a 1-2.5 micron camera optimised for use with the LLNL Lick adaptive optics system on the Shane 3 m telescope. Using diamond-turned gold-coated optics, the camera provides high efficiency diffraction limited imaging throughout the near-IR. IRCAL incorporates optimisations for obtaining high dynamic range images afforded by adaptive optics, coronagraphic masks, and a cross-dispersed silicon grism for high resolution spectroscopy.
