Research Abstract	We have started the development of the two-dimensional spectrograph for observation of Martian atmosphere. This spectrograph mounts an uncooled micro bolometer array(UMBA) which does not need a cryogenic systems and is small and light weight. In the present study, a diffraction grating of which the optics has fewer losses of the input radiance than germanium lens has been produced for the UMBA. It has made by a general-purpose processing machine and the surface tolerance has been evaluated. The result shows that the diffraction grating can be manufactured in low price.
