摘要: 在本论文中,研究了绕射/折射复合透镜的最佳单元组件,并将此研究的结果应用到十倍光学变焦镜头。
绕射元件具有材质轻,容易复制及符合经济效益的特点,它也具有一般折射透镜的成像功能。结合绕射元件及折射元件的复合型透镜,可以用来消除更多的像差,所以采用复合透镜,可以减少系统所需的片数,使系统重量减轻。
本论文即利用了光学软体对单片式和双片式的复合透镜进行追迹,分析其光学特性,并建立了最佳化的组合单元。再利用所建立的复合元件应用到十倍光学变焦的镜头设计上,来观察此最佳组合单元的结果实际应用到光学系统上的情形。
In this thesis, we study on optimum units of diffractive/refractive hybrid lens and ,based on the results, design a 10X zoom lens which can be used in camera system.
The diffractive lens is characteristic of thinness, lightness and cost effective. The diffractive lens has the same imaging function as refractive lens. The hybrid lens which consists of diffractive element and refractive element can eliminate more aberrations, and will not increase the volume and weight.
We simulate and analysis the singlet and doublet of hybrid lenses. From the simulated results, we find optimum units of the hybrid lenses. Finally, based on the optimum units, we design a 10X zoom lens.
