The figures of optical system, longitudinal aberration and modulation transfer function (MTF) are given.
给出了光学系统图、纵向像差图及调制传递函数图。
Optimized result indicates that the dispersive objective based on the proposed configuration has small longitudinal aberration, a large ACA, and a long working distance.
光学优化设计表明，具有正负透镜分离结构的色散物镜可以得到低的球差和大的轴向色散，而且具有较大的工作距离。
