I have no idea the specifics of the Nikon universal achr-apl con.a 1.4, but I made some replacements for some AO condensers that work well with all the condensers AO made that I have to try, about 6 or 7 models.Greg Howald wrote: ↑Wed Sep 07, 2022 4:01 amYes. But finding the right lens may be difficult I sometimes wonder if the people who make lenses for spectacles might be able to help in that regard but I have never asked .
I'm certainly not an optical expert, but I think matching diameter of the lens and the condenser, as well as having a short focal length (25mm for the AO) seemed to work pretty well. I don't recall the price I paid for the lenses offhand, but I believe it was less that $10.00.
