| 介绍了一种自动验光仪中调焦光学系统。通过研究自动验光仪中调焦光学系统的光学成像特性,首先建立调焦组的移动量与屈光度之间的关系,设计出系统的初始结构参数;然后在Zemax中建立相应的调焦光学模型,通过选取9个典型屈光度对结构参数进行优化;最后对优化结果进行分析与讨论。分析结果表明:所设计的调焦光学系统对-22D,-10D,-5D,-1D,1D,5D,10D这7个典型屈光度进行验光是可行的。 |

| A focusing optical system for the auto refractometer is proposed. By studying on the optical imaging properties of the focusing optical system in the auto refractometer, firstly a relationship between the movement of the focusing component and diopter is built, and the initial structural parameters of system is designed. Then, the focusing optical system is modeled by using Zemax software, and 9 typical diopters are selected to optimize the parameters. Finally, optimization results are analyzed and discussed. The results show that it is feasible for the focusing optical system when the typical diopters are -22D, -10D, -5D, -1D, 1D, 5D, 10D. |
