An imaging spectrometer has ben designed as a new instrument for remote sensing of the atmosphere. The design has been focused on applications in the field of weather forecast, climate research and atmosphere chemistry research. The push-broom type of instrument consists of a wide field of view telescope, in combination with three spectral channels. The instrument operates without a scanning mirror. Each channel contains a grating, imaging optics and a state-of- the-art 2D CCD detector. The channel separation is performed by a dichroic filter. A sunlit diffuser is applied for the in-flight radiometric calibration and the spectral calibration of the instrument. The polarization sensitivity is minimized by the application of a polarization scrambler. The basic instrument module consists of a UV-channel, a visible channel and a NIR-channel. The main new features of the instrument are a fast and high-resolution coverage of the atmosphere, in combination with high-resolution spectral measurements. This performance is realized in a rather compact instrument. The modular instrument configuration enables an easy adaptation of the instrument for different spectral bands.
