Hello.

I've managed to purchase used, but still working device, which uses high temperature and vacuum, to de-laminate glued lens elements.
I de-laminated several glued lens components using it (will post pictures later) and they appear to be fine.
I'm interested, whenever someone will require such service, and how much he'll agree to pay?

The process itself is very complex, requires very slow temperature adjustment and takes about 10 days. Considering the amount of electricity consumed, using it for single order is not a good idea, a batch of at least 10 lenses is needed, I believe.

Any ideas?

Does this work only with Canada balm glued lenses, or with new lenses with UV glued glue too?

Good question. Have to try. If you suggest me a modern lens with UV glued components, I'll give it a try.

I suppose you can get test samples with all Autofocus lenses (except perhaps those very early ones for manual cameras). So a cheap defect Sigma, Tamron, Canon, Nikon AF type zoom lens will help.

Good question! Most modern lenses use UV hardened lens cement to bond lens elements.

I have an achromatic doublet that is delaminating along its outer edge. So I could use this sort of service, but it's the only lens I have right now that needs this type of repair. This is an older lens, so I'm assuming it is cemented using Canada balsam. So keep us posted.

I have a Nikkor 35mm f2 which could be done
are you diasassembling the units or how do you want to do this?
I think new lamination must be checked in the lens barrel and in the optical assembly before shipping
and where are you lokated?
