Abstract:	本計畫提出使用Matlab計算三片鏡組最佳值設計，首先利用三片透鏡校正三階縱向色差方法，選取三片玻璃材料，再以優化程式控制三階球面像差、三階彗星像差與三階像散。其中三階球面像差校正軸上像差，三階彗星像差與三階像散校正半視角20度離軸像差，但半視角20度像差雖減少，軸上像差反而增加，所以同時調整三階球面像差、彗星像差與像散，分別校正軸上像差和半視角20度離軸像差。最後調整鏡片厚度與間距，降低半視角14度離軸像差，可得三片鏡組全領域最佳值設計。 ;The plan proposes using Matlab to calculate the optimal triplet design. First, the triplet is used to correct the third-order longitudinal chromatic aberration. Three glass materials are selected, and then the optimization program is used to control the third-order spherical aberration, third-order comet aberration, and third-order astigmatism. The third-order spherical aberration corrects the on-axis aberration, the third-order comet aberration and the third-order astigmatism correct the 20 degree off-axis aberration, but although the 20 degree off-axis aberration decreases, the on-axis aberration increases, so the same time, the third-order spherical aberration, coma aberration, and astigmatism were adjusted to correct the on-axis aberration and the 20-degree off-axis aberration, respectively. Finally, the lens thickness and spacing of the lenses are adjusted to reduce the off-axis aberration of 14 degrees, and the best design of the triplet in the whole field can be obtained.
