  TIRCAM2 (TIFR Near Infrared Imaging Camera - II) is a closed cycle cooled
imager that has been developed by the Infrared Astronomy Group at the Tata
Institute of Fundamental Research for observations in the near infrared band of
1 to 3.7 microns with existing Indian telescopes. In this paper, we describe
some of the technical details of TIRCAM2 and report its observing capabilities,
measured performance and limiting magnitudes with the 2-m IUCAA Girawali
telescope and the 1.2-m PRL Gurushikhar telescope. The main highlight is the
camera's capability of observing in the nbL (3.59 microns) band enabling our
primary motivation of mapping of Polycyclic Aromatic Hydrocarbon (PAH) emission
at 3.3 microns.
