【摘要】 在云南天文台多波段太阳光谱仪的改造中,将光谱拍照装置由原来的硬片落片改为软片走片,提高了时间分辨率。该专用照相机设计合理,结构紧凑,画幅大,曝光均匀性好,振动小,快门的可靠性高,能自动曝光和自动卷片,是一种理想的太阳光谱仪专用照相机。更多还原

【Abstract】 In the course of the technical transformation of a multi-waveband solar spectragraph of the Yunnan Observatory, the original falling-plate devise of the spectral photographic system is changed into the film conveyer, thereby increasing the time resolution tenfold or twentyfold. The special-purpo.se camera developed for the solar spectragraph has many characteristics such as greater frames, good uniformity of exposure of each frame, automatic exposure, automatically reeling the film in, small amplitude of vibration of the magazine, etc.; and therefore it is one of the ideal cameras attached to a solar sp’ectragraph and is worth while to be widely popularized.更多还原
