"After World War II, low energy costs gave impetus to the concept of the tall Building as a glass prism, an idea originally put forth by Le Corbusier and Ludwig Mies van der Rohe in their visionary projects of the 1920s."

在第二次世界大战后，低能源耗损的想法刺激高大建筑作为玻璃棱镜的概念；这个观念原初是科比西埃和密斯范德罗厄在1920年代富于远见的计画中所提出。

Our research work of combination of iceland and glass polarizing prism is based on four points: select suitable material、 calculation、 machining and testing. Select suitable material means that select the optical glass and glue that can match with iceland suitably; The optimal design scheme of prism is determined by calculation and analysis; The samples are machined, solving the technical problems, such as the matching of material and increasing transmittance; We pay attention to the transmittance and extinction ratio of prism in experimental test.
