An uv three-channel photographic photometer designed for broadband photometry of uv-rich stars is described. The optical design consists of two instruments. First, an off-axis telescope, imaging a 7 degrees x 9 degrees field of view, simultaneously records two channels centered at 1878 A and 2970 A (636-A FWHM). The second is a Schmidt-Cassegrainian telescope imaging a 5 degrees x 7 degrees field of view at lambda(eff) = 2574 A (358-A FWHM). Thirty-four star fields have been observed including the Large and Small Magellanic clouds, the nucleus of the Andromeda galaxy, and galactic nebulae in the Carina, Orion, and Taurus regions. More than 3000 stars have been recorded at 2574 A with a limiting visual magnitude approaching 12. A short discussion concerning the behavior of the emulsions is given.
介绍了一种用于富含紫外线恒星宽带测光的紫外三通道照相光度计。光学设计由两台仪器组成。首先，一台离轴望远镜，对7度×9度的视场成像，同时记录以1878埃和2970埃为中心的两个通道（半高宽为636埃）。其次是一台施密特-卡塞格伦望远镜，在有效波长为2574埃（半高宽为358埃）时对5度×7度的视场成像。已观测了34个星场，包括大麦哲伦星云和小麦哲伦星云、仙女座星系核以及船底座、猎户座和金牛座区域的星系星云。在2574埃处记录了3000多颗恒星，极限目视星等接近12等。还对乳胶的性能进行了简短讨论。
