등가렌즈 변환법을 2매 접합렌즈계의 설계에 적용하여 achromatic doublet 과 aplanatic doublet을 설계하였다. 먼저 얇은 렌즈계에서 3차수차를 보정하고, 이를 등가렌즈 변환법을 사용하여 두꺼운 렌즈계로 변환하였다. Crown 유리 BaK-2와 flint 유리 SF-2를 사용하여 Fraunhofer type 과 Steinheil type의 접합렌즈계를 설계하였고, 얇은 2매 접합렌즈계에서는 두 가지 설계형태 모두에서 2개의 achromatic solution과 하나의 aplanatic solution이 존재하였다.

The equivalent lens conversion technique is applied to design achromatic doublet and aplanatic doublet. A thin doublet which has zero axial thicknesses, are corrected for the third order aberrations at first, and the thin doublet is converted into thick lens system by using the equivalent lens conversion. Two types of cemented doublets, the Fraunhofer type and the Steinheil type, are designed by using a crown glass BaK-2 and a flint glass SF-2. In the thin doublet design, there are two achromatic solutions and a aplanatic solution for the both types.
