繞射/折射複合透鏡最佳單元組件研究

Abstract

在本論文中，研究了繞射/折射複合透鏡的最佳單元組件，並將此研究的結果應用到十倍光學變焦鏡頭。 繞射元件具有材質輕，容易複製及符合經濟效益的特點，它也具有一般折射透鏡的成像功能。結合繞射元件及折射元件的複合型透鏡，可以用來消除更多的像差，所以採用複合透鏡，可以減少系統所需的片數，使系統重量減輕。 本論文即利用了光學軟體對單片式和雙片式的複合透鏡進行追跡，分析其光學特性，並建立了最佳化的組合單元。再利用所建立的複合元件應用到十倍光學變焦的鏡頭設計上，來觀察此最佳組合單元的結果實際應用到光學系統上的情形。

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.
