非球面光锥的设计

The design of an aspherical cone of optical system

介绍一种大视野角实心光锥系统的设计方法,其中包括设计的难点、研究思路、解决方法及实际结果.传统的透射式光学系统要做到大视野角的能量汇聚,一般结构比较复杂,镜片数量多,即使只进行适当的像差校正也相对困难,而此实心光锥系统与传统透射式光学系统相比,具有成本低、结构简单、安装调试方便等显著特点。该光学系统主要用于大视野角近红外光的汇聚采集,可以根据实际运用要求进行相应的参数修改,从而用于其它波段的能量汇聚系统中。

The optical design of an aspherical cone system of wide field angle is introduced.The introduction includes the point difficulties,the design considerations,the solutions and the final results.Comparing to the past optical system,it has three noted characters,low cost simple configuration and setting an debug of convenience.The system is used to gather near infrared in wide field angle.The parameter can be modified according to actual application,so it can be used to other light-wave optical design.
