DESIGN AND PERFORMANCE OF THE OKAZAKI LARGE SPECTROGRAPH FOR PHOTOBIOLOGICAL RESEARCH
抄録
<jats:title>Abstract</jats:title><jats:p>A computer‐operated spectrograph was recently built at Okazaki, Japan. Different specimens can be placed on a horseshoe‐shaped focal curve (10 m long) covering a wavelength range of 250 to 1000 nm so they can be irradiated simultaneously. The linear dispersion is about 0.8 nm/cm. The photon fluence rate on the focal curve is 5 x 10<jats:sup>15</jats:sup>. photons x cm<jats:sup>‐2</jats:sup> x s<jats:sup>‐1</jats:sup> at 300nm and 1 x 10<jats:sup>16</jats:sup> photons x cm<jats:sup>‐2</jats:sup> x s<jats:sup>‐1</jats:sup> at 600 and at 900 nm. The spectral half width is 5.5 nm or less on the focal curve. The stray light content is about 10<jats:sup>‐5</jats:sup> of the main peak at the peak wavelength ± 100 nm. Specimens are set in microcomputer‐controlled threshold boxes so that wavelengths, photon fluence rates, photon fluences and timing of irradiations are controlled automatically according to a pre‐programmed schedule. An optical fiber system is also provided for remote irradiations.</jats:p>
