HiCIAO, the High-Contrast Coronographic Imager for Adaptive Optics, is a coronographic simultaneous differential imager for the Subaru Telescope Nasmyth focus. It is designed primarily to search for faint companions, brown dwarves and young giant planets around nearby stars by differential imaging in and out of the Methane absorption in the H band. It can also be used as a simple adaptive optics imager and as an imaging polarimeter for the study of scattered light in the vicinity of stars and active galactic nuclei. HiCIAO will work in conjunction with the new Subaru Telescope 188-actuator adaptive optics system and the laser guide star system, both currently under construction. HiCIAO is designed as a flexible, experimental instrument that will grow from the initial, simple coronographic system into more complex and innovative configurations. HiCIAO uses warm coronographic foreoptics outside of the infrared camera cryostat, since the primary scientific use will be in the H band. The beamsplitting elements are LiYF4 single or double Wollaston prisms. The HiCIAO infrared camera is designed to minimize optical path differences for the two or four images generated by the beamsplitters. The camera lens is at ambient temperature and also serves as the cryostat window. The only cold optical elements are the filters. The camera uses a 2.5 μm HAWAII-2RG detector array operated by a Teledyne Sidecar ASIC that is operated at ambient temperature.
The HiCIAO instrument is expected to have first light at the Subaru telescope in the summer of 2007.
