The Canarias Infrared Camera Experiment (CIRCE): optical and opto-mechanical design and manufacture

摘要

We report on the design status of the Canarias InfraRed Camera Experiment (CIRCE), a near-infrared visitor instrument for the 10.4 meter Gran Telescopio Canarias (GTC). In addition to functioning as a 1-2.5 micron imager, CIRCE will have the capacity for narrow-band imaging, low-and moderate- resolution grism spectroscopy, and imaging polarimetry. CIRCE's all-reflective aspheric optical design offers excellent throughput and image quality. We present an analysis of the optical layout and the progress of the opto-mechanical design and manufacture.
