Bonjour,
effectivement cet objectif est pour l'usage avec un microscope inversé. Mème en débloquant la correstion pour aller à 0,5 ce serait encore loin de 0,17.
J'ai un problème simillaire avec un bon 40x acheté sur ebay dont la bague de correction de lamelle est bloquée. J'ai soumis cela à une liste de diffusion anglaise. Pierre H. m'a répondu par MP à l'époque.
Ci dessous les messages sur la liste de diffusion. (a lire de bas en haut)
2 conseils sortent:
- ne rien faire si on n'est pas capable de démonter remonter l'objectif
ou
-essayer quelques gouttes d'alcool isopropilique. Je n'ai pas encore essayé !
Qu'en pensez vous? est ce que je continue à l'utiliser bloqué ou est que j'essaie de faire quelque chose?
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. MARS

I am french. Sorry if I don't know the good words.
I have a problem with an olympus microscope lens from ebay.
It is quite new, but there is a ring for adaptation of " lamelle " high.
It is extremely hard to move this ring. I could put it on 0,17 from 0,11 but
it is quite impossible to change.
Do you know a solution to move it normally ?
Best regards
Daniel
