Abstract
Current work will be reported using an infrared spectrometer which employs a set of two-dimensional transparent and non-transparent zones in place of standard slits. The two-meter spectrometer is in a Littrow mounting using gratings of 300 grooves per mm with a ruled area of $180 \times 135 mm$. The wavelength coverage of the instrument is from 0.7 to 40 microns. Resolution of 0.05 to $0.1 cm^{-1}$ has been obtained with gains of luminosity of 130 times over those of conventional spectrometers for this region. The instrument is used in a single beam single-passed mode.
