Spectral Range


The SPS-300/SPS-400 Spectral Range (both Standard and High Resolution Models) is 2 to 2000cm-1 (5µm to 5mm or 60GHz to 60 THz). Although the SPS-300/SPS-400 optics can cover a spectral range from 2 to 2000cm-1, the practical range is generally limited by the source and detector combination used. For example, the 2cm-1 low wavenumber spectral range cutoff can only be obtained with a high powered source such as that of a synchrotron entering through the external light source port and a 1.7K helium cooled bolometer detector. Using the internal Hg arc lamp provided, the low wavenumber spectral range cutoff is limited to approximately 4cm-1 using the bolometer. This low wavenumber cutoff increases to about 8cm-1 with a 4K helium cooled bolometer and the internal Hg arc lamp.

At the high wavenumber end, the grid spacing of the polarizer is the limiting factor. Since Sciencetech uses a close pitch 4µm grid polarizer, compared to other polarizers of 12.5µm or 25µm pitch, the SPS-300/SPS-400 is capable of reaching 2000cm-1 if the detector and source allow. More commonly the cutoff is closer to 1000cm-1.
