Re: release of ring

First I'd try applying a little %70 or %99 isopropyl alchohol (rubbing
alcohol). DO NOT USE GASOLINE/PETROL! Gasoline stinks, is highly flammable
and contains numerous other chemicals and deposits all of which are not good
for any lense system. It will also leave a residue behind.

Apply a drop or two of alcohol and gently try moving the ring back and
forth. If you can get a littly movement, then apply a few more drops of
alcohol and move the ring back and forth again. Repeat until you are
satisfied with the results.

If you can not get it to move, then it must be repaired by a professional or
a competent amateur.

Good Luck.

Hi Daniel,
I guess that some immersion-oil is in the ring. Use gasoline. There is
a long discussion about which gasoline to use on microscopes some
weeks ago.

yours, heini

Heini and Daniel, Your right but wrong. Its not that oil got in the
objective, its that there is no oil left in the grease.

Grease is made up of a binder and an oil, in natural lubricants that
Olympus uses that oil will dry up after 5 years or so. I'll bet this
one is as dry as a bone. I'd take it to your local microscope repair
person and let him fix it, if you don't have the tools or training
this one could get tricky.

Thanks,
