高級相機鏡頭通常由六個以上的鏡片組成，以消除鏡頭的像差，提高圖像品質。 然而，這種笨重的鏡頭組合限制了相機鏡頭的小型化。 在這篇論文中，我們提出了一種由超薄超穎校正器和 Cooke triplet組成的相機鏡頭系統。 超穎校正器用於消除 Cooke triplet的球面像差。首先，我們使用商業軟體 ZEMAX 來計算超穎校正器的理想相位分佈。接下來，我們使用超穎校正器對 Cooke triplet的聚焦品質進行了數值分析。從光斑點列圖觀察，在加上超穎校正器後，Cooke triplet的光斑尺寸可以從49.02μm大幅縮小到0.428μm。 此外，超穎校正器提高了 Cooke triplet的圖像品質。而在加上超穎校正器後，Cooke triplet的空間頻率提高許多且接近繞射極限，從以上分析可以發現超穎校正器可以消除大部分的球差。

High-level camera lens usually consists of more than six lenses to eliminate the aberration of lenses and improve image quality. However, this heavy lens combination limits the miniaturization of the camera lens. In this work, we proposed a camera lens system which consists of an ultra-thin meta-corrector and Cooke triplet. The meta-corrector is used to eliminate the spherical aberration of the Cooke triplet. We used the commercial software ZEMAX to calculate the ideal phase distribution of the meta-corrector. We next numerically investigated the focusing quality of the Cooke triplet with a meta-corrector. The ray-tracing simulation shows that the focal spot size of the Cooke triplet can be significantly reduced from 49.02 μm to 0.428 μm after adding a meta-corrector. Moreover, the meta-corrector improved the image quality of the Cooke triplet. The spatial resolution of the Cooke triplet improved when a meta-corrector was added and is closed to diffraction limit
