Design of a new kind of multi-waveband large aperture parallel light pipe

GAO Ming-hui1,LI Li-fu1,XU Jing-li1,BAO Jin-he2(1.Changchun Institute of Optics,Fine Mechanics and Physics,Chinese Academy of Science,Changchun 130033,China;2.Aviation University of Air-Force,Changchun 130022,China)  
The parallel light pipe is usually used in the field of assembly and adjustment as the detection equipment for optical instrument.With optical instrument development for large aperture,long focal length and multi wave bands,both aperture and focal length of instrument will exceed application range of conventional parallel light pipe.In order to guarantee detection precision,the hypernormal parallel light pipe is used.It proposes the higher requirements especially for optical process,such as mechanical supporting,are necessary.A new style of large aperture parallel light pipe was provided aiming at the above problem.A new style of mechanical structure including apart flexible joint was provided on the basis of the application principle of the traditional parallel light pipe.The design structure not only could reduce difficulty in subsection connection among light pipes with long focal length and large aperture,but also could reduce weight of total light pipe so as to enhance efficiency and reduce manufacture cost to a great extent.
