Analysis and Correction of Chromatic Aberration and Monochromatic Aberration for Optimal Triplet Design by Using Matlab

Project Details

Description

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.
