Abstract

This method developes a system which consists of a single positive component, followed by a negative meniscus that is concave to the rear, followed by another negative meniscus lens that is concave to the front, and a final positive single lens. The stop is at the middle. Assume the same refractive index for those four elements and the power of the 1st element equals to that of the 4th, the 2nd element equals to the 3rd.
