Query: CIRCE: The Canarias InfraRed Camera Experiment for the Gran Telescopio
  Canarias   The Canarias InfraRed Camera Experiment (CIRCE) is a near-infrared (1-2.5
micron) imager, polarimeter and low-resolution spectrograph operating as a
visitor instrument for the Gran Telescopio Canarias 10.4-meter telescope. It
was designed and built largely by graduate students and postdocs, with help
from the UF astronomy engineering group, and is funded by the University of
Florida and the U.S. National Science Foundation. CIRCE is intended to help
fill the gap in near-infrared capabilities prior to the arrival of EMIR to the
GTC, and will also provide the following scientific capabilities to compliment
EMIR after its arrival: high-resolution imaging, narrowband imaging,
high-time-resolution photometry, imaging polarimetry, low resolution
spectroscopy. In this paper, we review the design, fabrication, integration,
lab testing, and on-sky performance results for CIRCE. These include a novel
approach to the opto-mechanical design, fabrication, and alignment.
