| 摘 要： | 应用像差理论,在ZEMAX软件中对里斯特型折射-衍射混合消色差显微物镜的几何结构、像差特性进行研究.通过分配折射-衍射混合元件的光焦度校正位置色差;通过调整透镜的形状因子、衍射面的相位系数、选择适当的光学玻璃材料,校正球差和彗差;利用残留色差平衡球差和彗差.设计得到的显微物镜由两片同种常规光学玻璃基底的单透镜构成.研究表明:在光学设计中合理地应用衍射元件色散性能,可以设计出具有成像质量好、结构简单、质量轻的镜头.

| Abstract: | In this paper,the structure and aberration of a hybrid refractive-diffractive achromatic Liszt microscope objective are examined theoretically using the ZEMAX software.Its axial aberration is corrected by distribution of power of hybrid refractive-diffractive lenses.The spherical aberration and coma are corrected through adjustment of the shape factor and diffractive surface phase coefficients and choice of proper optical glass.And residual chromatism is used for balancing its spherical aberration and coma.... |
