ABSTRACT
Japan. The spectrograph has been used actively for interuniversity-in Japan and partially international-cooperative programs. For more advanced studies, a more powerful and effective large spectrograph is needed. A symposium on "New Prospects of Photobiology and the Future Plan of the Okazaki Large Spectrograph" was held in November 1996 at NIBB. In this symposium, the future plan of the large spectrograph, which is called as the super spectrograph, has been proposed. The spectrograph will be designed to obtain high-intensity, monochromatic radiation. A paper presented at this symposium, indicated that the major structure of the super spectrograph will be a collection and simultaneous use of nearly 60 newly developed high-power tunable lasers that cover 200-1000 nm and provide at least one or two orders of magnitude higher intensities (after beam expansion to a 5-cm diameter) than the OLS. If the super spectrograph is constructed in the near future, the exposure experiments with monochromatic radiation will be conducted more actively and efficiently.
