Hi everybody,
Total noob here, Sorry about stupid question.
I was reading some patent and lectures on cooke triplet and I am trying to buy lenses involved separately.
My problem is that I do not know how to search the internet by the curvature and the thickness (and diameter of the lens). Is it possible or all lens sellers do it by the focal distance and/or lens power?
I am in need of a lens with radiuses of 40 and -47 and the thickness of 1.
Sorry again if it is a very irrational question.
Thanks for any helps and suggestions.
