| Outline of Final Research Achievements |
The purpose of the research is to realize the simultaneous 7-colour imaging camera by combination of TRIPOL with the existing SIRIUS on IRSF. The key is to develop the read-out system for a larger format CCD. However, we could not attain the miniaturization, so we searched for several bypasses, 1) Expansion of the Cassegrain focus box, b) Availability of alternative commercial CCDs, and 3) Planning to construction new telescopes. There are still not open routes to the satisfied solution. In the course of the search, we found a new optics: Aplanatic optics with spherical 1ry and 2ry mirrors. We also developed the method of the fabrication and measurement of the 4th aspheric mirror. Publication of TRIPOL to academic journals has been unsuccessful, because of the premature of the instrumental calibration, that is, the limit of the accuracy as the instrument was uncertain. Although TRIPOLs were distributed to several observatories and commissioned but still not fruitful.
