The main parts of the imaging spectrometer for observing ocean color (so-called OCM system) are discussed; the scan subsystem, the pre-position telescope, the dispersion element, and the spectrometer, which should be determined according to the science requirements of ocean color observation and the correspondent specifications of the optical design. An analysis of the optical systems of MODIS-T proposed by NASA/Goddard Space Flight Center shows some problems in them. Basing on these discussions, a reflection-refraction hybrid optical system by autocollimation grating was designed. The results are better than the improved MODIS-T optical design in some points. The minimal optical MTF value of this design at the Niquist frequency is better than 0.96, the construction is much more compact.
