| Outline of Final Research Achievements |
We designed a new near-infrared spectrograph for the 3.8m Seimei telescope built by Kyoto University in Okayama. The design is based on a non-conventional concept, and its development was started with a budget of about quarter for the usual near-infrared spectrograph. In the end, due to lack of budget, the spectrograph was completed up to about 70 to 80%, but new knowledge was obtained regarding : the fabrication of a large cryostat by electron beam welding, the production and inspection method of a large-curvature aspherical mirror, the low-cost tilt sensors and actuators for cooling vacuum use, and reduction software for images acquired by a multi-fiber spectrograph. Development of the spectrograph will be continued using other budgets.
