Abstract

We present the current status of the Canarias InfraRed Camera Experiment (CIRCE) an all-reflective near-IR, imager, spectrograph, and polarimeter for the 10.4-meter Gran Telescopio Canarias (GTC). In particular, we review the progress of the opto- and cryo- mechanical design and manufacture, focusing on the custom filter, lyot, and grism wheels, lightweight optics, and mirror brackets. We also outline our progress with the optical bench. Finally, we discuss a number of CIRCE's features that both complement and augment the planned suite of GTC facility instruments.
