The main parts of the imaging spectrometer for observing ocean color (OCM system) are: 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. The authors analyzed the optical systems of the MODIS-T proposed by NASA/Goddard Space Flight Center and found some problems in them. Based on this the authors designed a reflection-refraction hybrid optical system by autocollimation grating. The results are better than the improved MODIS-T optical design in some points--the minimal optical MTF value of the design at the Niquist frequency is better than 0.96, the construction is much more compact.
