一种新型多波段大口径平行光管的设计

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

平行光管是光学仪器装调、检测领域常用的标校设备。随着目前光学仪器向着大口径、长焦距、多波段方向的发展,仪器的口径与焦距都远远超出常规平行光管的适用范围。因此,为了保证其检测精度,需使用超出常规的平行光管,这就给光学加工,尤其是机械支撑提出了很高的要求,针对此问题提出了一种新型的大口径平行光管的设计,在传统平行光管应用原理的基础上,采用一种分体式软连接新型机械结构,该设计结构不仅可以降低长焦距、大口径光管的分段连接难度,而且减轻了整个光管的质量,从而可以很大程度上提高检测、装调的效率,降低制造成本。

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.
