The Cananea near-infrared camera (CANICA) is an instrument commissioned at the 2.12m telescope of the Guillermo Haro Astrophysical Observatory (OAGH) located in Cananea, Sonora, México. CANICA operates in the near-infrared at multiple bands including J(1.24µm), H(1.63µm) and K (2.12µm) broad-bands. CANICA in located at the Ritchey-Chrétien focal plane of the telescope, reimaging the f/12 beam into f/6 beam. The detector is a 1024 × 1024 HgCdTe HAWAII array of 18.5µm pixel size, covering a field of view of 5.5×5.5arcmin2, for a plate scale of 0.32arcsec/pixel. The camera is enclosed in a cryostat, cooled with liquid nitrogen to 77K. The cryostat contains the collimator, two 15-position filter wheels, single fixed reimaging optics and the detector.
