Hello everyone I need a bit of advice. I have the much vaunted Zeiss planapo x63 na 1.4 objective. Like a lot of these it has some delamination, in this case...
This objective needs to be used with an immersion condenser otherwise the NA will be limited to just under 1.0 anyway. To get best resolution set up Köhler...
Thanks Don In fact I always use my high mag planapos with slide oiled both sides. I have to say the only objectives where the resolution advantage of oiling...
Hello Steve and "Tools" -- I have been working with polarizing (geological) microscopes for many years, and an AO 110 polarizing scope (not sure if AO still...
Clean the blades and reassemble without anything. Lubricant will collect dust and your diaphagm will be ruined. Dry is the best. emile ... iris ... but ... ...
Hi Ray, Don is correct, there is no cure for delamination, other than having your objective completely overhauled at factory. Since your objective is...
Hello Emile, How would you recommend cleaning the diaphragm - immersion in an appropriate solvent, e.g. heptane/xylene/chloroform or some other? It seems these...
Wonderful experience, those high NA lenses. We use them routinely on inverteds at condenser NA 0.5. (live phytoplankton in 1ml chambers). I think that's...
Emile, I understand that dry leaves are best. Have you or anyone else here had experience with dry graphite powder for lubrication (I've already used it, so I...
Hi Don/René Thanks for responses. Still not sure of the theory here (my original questions). I have always shut my iris to the outer cone of light, but every...
Thanks for the information...it is appreciated. Do you have any idea where documentation for the AO scope you have might be on line? I am trying to understand...
Hi Mike, I usually use alcohol, and if it is not good enough, The company Shandon make a xyleen substitute called "Histosolve". I cannot recommend chloroform,...
Hi Jim, Graphite powder is a good lubricant, but usually an iris diaphragm is on the top of an optic (lens or mirror). Using the diaphragm will deposit this...
Hi, I have a copy of the AO 110 biological scope manual but not the polarizing version. No idea where to get one, sorry. You can probably get most of what you...

Hi Emile Now, don't laugh out loud. I am an engineer and have a lot of experience designing and manufacturing small complex objects. Someone put the x63...
Hello Emile, Thanks for the quick response. I've just finished cleaning three of the Orthoplan field diaphragms using xylene, toluene and or acetone and was...
Hi Ray, I will not laugh out loud. This group exchange ideas and everybody is free to do so. I recommend the factory, because of three reasons: 1) The...
Hello, I keep a small ultrasonic cleaner for cleaning my parts. This model is sold for cleaning jewelery, eye glasses, etc. and only cost ~$20.00 to $25.00 at...
I have the same ultrasound unit, but I never separate my items from the bath water. Why should I? thanks, doug ... From: "uca_minax" <uca_minax@...> To:...

Hi Don, The avi 304-7 is very interesting, but 295 is truly fascinating. Any idea of what type of amoeba this is, and do you think it can be found easily in...
Hi Ray, The theory is complicated, with most of the details far beyond my own understanding, but I can give my best attempt. When the light goes through the...
I place the parts and solvent in a jar for two reasons. The first is the unit is not rated as a nonexplosive device and some of the solvents I use are...
