Denis taylor and made with early schott glass, it is visually just as free from false color as a modern apochromat with the latest glasses, thanks to the long f/ratio. The 'cooke triplet' is the common generic design of triplet lens, like rodenstock's geronar, among others. The simplest design that is capable of correcting all of the seven seidel aberrations over a wide field of view is the cooke triplet. Next i attempted to correct the two first order chromatic aberrations while losing as little as possible of the monochromatic correction.

In 1950 a specific triplet was invented and patented by eastman kodak (ef=100mm, f/1.9) and we will look at how to recreate it in geomagic design using scripting. The front element has one focal length, the rear element a different focal length, and by screwing them together the whole intact lens has a shorter focal length. Explanation of triplets from.
