this was in a time where opthalmic hi index plastics were very limited and on a number of occasions we had to strip multicoatings off some of their 1.8 refraction glass in an acid bath
all technology of course is now in hi index plastic lenses and glass is pretty much obsolete, it has been greater than fifteen years since i have dispensed a glass lens
i will phone my friend in the laboratory today
btw in my experience there are no "other" special coatings inert on glass that cannot be removed as wavytone mentions, anyhow i will ask
pat
Cheers Pat,I have a friend who is into eyepieces and will ask him if it is possible to do it and maybe just send the front element to you.
Look forward to what your friend in the lab says.
Cheers
