McLean et al. (eds.) (printed in the Netherlands), 106-108, 1997. DENIS 3-Channel Near-Infrared Camera Imager The DENIS (Deep European Near-Infrared southern sky Survey) instrument is a 3-channel camera developed by the Observatoire de Paris with input from several European institutions. It was utilized for the DENIS survey at the ESO 1.0 meter telescope in La Silla, Chile, and features different characteristics for its I, J, and Ks channels, including various wavelengths, array sizes, and quantum efficiencies. The instrument’s specifications include read-out noise, exposure times, and limiting magnitudes, making it capable of detecting faint celestial sources. For detailed information about the DENIS instrument, refer to the work of Epchtein (1997).
