Seperating lens

[peter_hall3]

I have a question, can replacement elements be made for an old lens. The current

one is separating pretty badly. This lens was given to me and is over 100 years

old. I have new lenses but this is kind of a pet project. Any suggestions would

be helpful.

It would be difficult to make new glass elements: you would have to know the glass type,

then would have to grind and polish the new elements to the same thicknesses and

curvatures as the existing elements. It would be much easier to uncement the elements that

are separating, and recement them. S. K. Grimes has an article about the process at

If the elements aren't busted, it's possible to get lenses re-cemented. Sorry, I don't have any specfic places I can give you, but I can say with some confidence that it won't be inexpensive.

I've never sent anything to Focal Point, but they do have a good reputation.

I did it on a couple of occasions. There is a fine mechanic in

Krakow, Poland who does all kind of precise adjustments and

repairs. I visit them when I am there and need a repair being

made. It is not expensive. Certainly, a fraction of the cost here in

NYC.
