We applied the PtSi IR CSD to the astronomical instrument fabricated in National Astronomical Observatory Japan. Rapid progress in infrared array detectors enables us imaging observations just like the observations with photographic plates, with higher sensitivity. The PtSi IR CSD is developed and processed by Mitsubishi Electric Co. in Japan. The PtSi Schottky barrier diode array has not high quantum efficiency but an excellent uniformity and stability, a large format size and a low read-out noise. We carried out the wide field infrared observations with PtSi camera. The ultimate goal of our project is to build a large format mosaic array camera for Japan 8 m telescope project 'SUBARU' in Hawaii that was just started in 1991.
