We present details of characterization and imaging performance of the Cananea Near-infrared camera ( CANICA ) at the 2.1 \mathrm { m } telescope of the Guillermo Haro Astrophysical Observatory ( OAGH ) located in Cananea , Sonora , México .
CANICA has a HAWAII array with a HgCdTe detector of 1024 \times 1024 pixels covering a field of view of 5.5 \times 5.5 \mathrm { arcmin ^ { 2 } } with a plate scale of 0.32 \mathrm { arcsec / pixel } .
The camera characterization involved measuring key detector parameters : conversion gain , dark current , readout noise , and linearity .
The pixels in the detector have a full-well-depth of 100 , 000 \mathrm { e ^ { - } } with the conversion gain measured to be 5.8 \mathrm { e ^ { - } / ADU } .
The time-dependent dark current was estimated to be 1.2 \mathrm { e ^ { - } / sec } .
Readout noise for correlated double sampled ( CDS ) technique was measured to be 30 \mathrm { e ^ { - } / pixel } .
The detector shows 10 % non-linearity close to the full-well-depth .
The non-linearity was corrected within 1 % levels for the CDS images .
Full-field imaging performance was evaluated by measuring the point spread function , zeropoints , throughput , and limiting magnitude .
The average zeropoint value in each filter are J = 20.52 , H = 20.63 , and K = 20.23 .
The saturation limit of the detector is about sixth magnitude in all the primary broadbands .
CANICA on the 2.1 \mathrm { m } OAGH telescope reaches background-limited magnitudes of J = 18.5 , H = 17.6 , and K = 16.0 for a signal-to-noise ratio of 10 with an integration time of 900 \mathrm { s } .
