  The present invention relates to an optical resin comprising a poly(benzoazole) having repeating units represented by the following general formula (1) as a constituent; and an optical waveguide, an optical filter and an optical lens prepared using the optical resin: 1 wherein R 1 represents a tetravalent organic group having an aromatic ring, N and X in each of the two sets thereof are linked to two atoms at the ortho-position on the aromatic ring of R 1 to form a 5-membered ring, R 2 represents a divalent organic group and X represents an oxygen atom or a sulfur atom. The optical resin of the present invention has high transparency to light rays falling within the near infrared region, shows only small changes in the refractive index and the rate of birefringence as a function of wavelengths of light rays used for the measurement and falling within the near infrared region, has a low rate of birefringence and has high heat-resistance. Therefore, the optical resin of the present invention is suitably used as a resin for preparing optical parts, which are employed for the light rays falling within the wavelength range used in the optical communication.

  本发明涉及一种光学树脂，其成分包括具有下式（1）所代表重复单元的聚苯并唑；以及使用该光学树脂制备的光波导、光学滤波器和光学透镜： 1 其中 R 1 代表具有芳香环的四价有机基团，两组有机基团中的 N 和 X 分别与 R 1 芳香环上正交位置的两个原子相连 1 形成一个五元环，R 2 代表二价有机基团，X 代表氧原子或硫原子。 本发明的光学树脂对近红外区域内的光线具有较高的透明度，折射率和双折射率随用于测量的近红外区域内的光线波长的变化很小，双折射率较低，并且具有较高的耐热性。因此，本发明的光学树脂适合用作制备光学部件的树脂，这些光学部件用于测量光通信所用波长范围内的光线。
