A compact spectrometer operable in a wavelength range of 4.5 or more microns includes an entrance slit, a collimating mirror, a grating, a focusing mirror and a two-dimensional array of detectors. At least some radiation passing through the slit follows a path that is reflected by the collimating mirror onto the grating, which in turn reflects at least some radiation onto the focusing mirror, which in turn reflects and focuses at least some radiation at a first focal plane and onto the detector array. Each column in the detector array corresponds to a wavelength in the 4.5 or more micron range, the detector array includes a plurality of columns that collectively correspond to wavelengths spanning the 4.5 or more micron range, and each adjacent pair of columns in the detector array corresponds to two wavelengths that differ by an equal amount.
