Abstract
We investigate the use of non-cryogenic instrumentation for near IR spectroscopy. With this technique, it is possible to apply in the J and H bands some instrument concepts and observing techniques used in the visible. We present observations of the thermal background in H. We derive some instrument requirements for minimizing and handling it. We recommend the use of short wavelength cutoff wavelengths or linear filters in H. We present observations of the sky emission, and do confirm previous upper limits of the continuum emission between the OH lines. We discuss some applications of non-cooled near IR spectroscopy.
