An imaging spectrometer design has been demonstrated which utilizes a plano blazed diffraction grating in divergent light. It offers important advantages over traditional collimated light spectrometers using either a grating or a prism. This design in a simple, compact configuration has linearity in wavelength and field and uniform spacing of wavelengths with no geometric distortion (smile). In addition to these features, polarization sensitivity and radiometric efficiency of the design will be discussed and compared with the requirements for the High Resolution Imaging Spectrometer (HIRIS) for the Earth Observing System.
