I am hoping I can get some direct measurements and information from anyone who happens to own a Hypergon lens, of any focal length! Also, paging Nodda Duma...or anyone else with lens design / manufacturing expertise.
I have acquired a batch of optical elements which the seller claims to be Hypergon lens elements. These are extremely curved elements that certainly look the part. I took a gamble on these because it seems possible, and I have 3 sets.
I would love to have some direct measurement of Hypergon elements from owners, that could perhaps point me in the right direction as to what focal length these would be for and/or other information that might help me nail down what I've got - for example, what is the separation between elements for a given focal length? Is the design simply enlarged for each size up?
I know that mounting/making these into actual lenses will not be easy or cheap but I am hoping I can somehow, and then get 3 more lenses out into the wild. Well, 2 anyway, as I'll keep one!
Here's some photos that the seller posted. Note the number written on the element. The elements themselves are about an inch and a half wide - quite large really, which makes me wonder if it's one of the longer focal lengths.
Thanks!
