    • This invention relates to optical elements for radiation which comprises a graphite film obtained from a film of a polymer such as polyphenylene oxadiazole, polybenzothiazole, polybenzobisthiazole, polybenzooxazole, polybenzobisoxazole, polypyromellitimide, polyphenylene isophthalamide, polyphenylene benzoimidazole, polyphenylene benzobisimidazole, polythiazole or poly-p-phenylene-vinylene The graphite film is obtained by pyrolysis of the polymer film at 2800°C or higher at a pressure of not lower than 4 kg/cm² in vacuum or in an inert gas. Alternatively, the element may be made of a graphite film obtained from the polymers mentioned above and intercalated with a metal halide. The intercalated films are readily bonded by pressing in the form of a thick sheet or block. Still alternatively, the graphite films and the intercalated films may be superposed alternately and bonded by pressing, or the intercalated films may be sandwiched between the graphite films and bonded together to form a thick sheet or block. The optical element has application as a lens, monochromater, filter or analyzer for radiations
    • 本发明涉及用于辐射的光学元件,其包括由聚苯乙烯恶二唑,聚苯并噻唑,聚苯并双噻唑,聚苯并恶唑,聚苯并双恶唑,聚吡喃单酰亚胺,聚苯撑间苯二甲酰胺,聚苯并咪唑,聚苯撑苯并咪唑,聚噻唑或聚对苯二甲酸, 亚苯基亚乙烯通过聚合物膜在2800℃或更高的压力下在真空或惰性气体中以4kg / cm 2以上的压力进行热分解,得到石墨膜。 或者,元件可以由由上述聚合物获得的石墨膜制成,并插入金属卤化物。 嵌入的膜通过以厚片或块的形式压制而容易地粘合。 或者,石墨膜和嵌入的膜可以交替叠置并通过压制结合,或者插入的膜可以夹在石墨膜之间并结合在一起以形成厚的片或块。 光学元件作为透镜,单色仪,过滤器或辐射分析仪具有应用
