Novel spectrometer arrangements are described. They may employ a resin-based preconcentration system to sample chemical vapors. A field-widened interferometer modulates radiant energy. The signal generated by the interaction of the radiant energy with the sample is detected and processed by a computer. A variety of enhancements to the basic design are described, providing a family of related spectrometer designs. These spectrometers have applications in spectrometry, spectral imaging and metrology.
