This post offers a draft of Chapter 8:

Chapter 8:  How to Make Lenses That Are Good Enough for Photography

(pdf, 276 KB)

This one concerns the complexity of modern lenses required to correct aberrations, minimize flare, etc.  It is fairly brief, but it covers a lot of ground.  As always, comments are appreciated.  I would certainly like to correct errors and misconceptions; but I also need to find out what parts are not understandable as written.

I enjoyed the essay very much, but according to my limited knowledge of optics, the aberration shown in figure 2 is curvature of field and not spherical aberration.

Thanks Bill, You are correct. I was illustrating image curvature, not sperical abberation (SA). In fact, I don't have any real of simulated examples of SA. I have changed the caption.
