A near-infrard (10 microns-2.5 microns) camera in use at the Canada-France-Hawaii Telescope and at the Observatoire du Mont Megantic 1.6 m telescope is described. The camera is based on a NICMOS3 256X256 HgCdTe array detector. While it is used for broad-band imaging and polarimetry through the standard J, H, and K filters, a distinguishing feature of its design is the use of circular variable filters for spectral line imaging in regions of strong continuum emission. The control system was designed to minimize overhead and be simple to use and to maintain. The performance of the instrument is described and illustrated with images of the H2 emission from the Cepheus A star formation region and a K-band image of the environment of the quasar 3C 345.
