Special-Purpose Camera Attached to A Multi-Waveband Solar Spectragraph

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-purpose 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 oi vibration of the magazine,etc., and therefore it is one of the ideal cameras attached to a solar spectragraph and is worth while to be widely popularized.
