Thanks for that Rene, and thanks for your comments regarding sticking with a series of objectives. But that having been said, how do you identify a series... ...
Hi again, In a recent post I mentioned a recently purchased Olympus E, including a 0.9 condenser with swing-out Whilst testing the 40x lens I noticed an...
... Hope not, not suppose to be anyway. Yeast is round and colourless. Wine contains up to 1% of tartrate (normally .65%), which I had precipetating in my...
Well, if the oil is inbetween lenses, and it's swing out, get the oil away with filterpaper moistened with cleaning petrol. Try to use as little as possible....
Hello, Currently I have a no-name basic microscope. I have duck pond across the street from me and I have started looking at water samples. Most of the...
Hi, You might want to download a copy of OPTICAL MICROSCOPY by Davidson and Abramowitz, available as a pdf download from this page if you don't already have...
A Phase Contrast scope will do BF just fine -- also DF. You don't need a BF condenser in addition to the Phase Condenser, nor do you need BF objectives in...
and.. a very nice site it is! Hi, You might want to download a copy of OPTICAL MICROSCOPY by Davidson and Abramowitz, available as a pdf download from this...
Dear Jonathan, Sticking with one brand of microscope, eyepieces an stands will reduce the problems you face. But as you note it doesn't eliminate them. Unless...
TMT, That is a pretty rare Phase Inverted Tissue Culture microscope from Nikon. Note the date on the ammeter at 1964 - mid 1960's would indeed have been my ...
Thanks for the reply Steve .. it was very informative. It makes more sense now since in the description it said: BF, DF and Phase 1 through 3. Regards, Gary...
Hello When mounting heavy residue minerals what mounting media (RI) to use Canada balsam or something different Thanks David [Non-text portions of this message...
Over the years I have seen wooden drawer inserts for the Zeiss microscope lines. I would assume that they were made for the Ultraphot and the Universal...
Hey TMT, Many optics were packaged as "kits" in fitted wooden boxes, and this practice was common for all the major manufacturers: Zeiss, Leitz, Reichert, ...
David, What do you mean by heavy residue minerals? Most minerals (rocks) are mounted in epoxy or other hard resin that are going to be viewed as thin sections...
I've seen a number of posts on aligning binoc heads, mostly saying run away, don't do it, not worth it, etc. This is the sort of encouragement I can't ignore,...
Hi David, The answer is that Zeiss did not make that item. There are itermediate pol bodies and Optovars but no combinations. As a paractical matter, while I...
Hi, That is a complete transmitted light DIC setup. Although it was used on the Universal series it will also work on the Standard Series. The slide is not a...
Hi Don, Zeiss made two different turret condensers, one has positions I,II,III,and IV plus phase Contrast 2 and 3. Another condenser has positions I,II,and...
Hi Gordon The heavy residue you get from river deposits by panning David ... From: Gordon Couger To: Microscope@yahoogroups.com Sent: Saturday, April 01, 2006...
If you mount them whole in the field both epoxy are norland 0 are easy to use. In every case try a few sidles of subjects & materials in the lab matching...
Nope, Aaron, you have been mistaken. For some stupid reason ZEiss decided to use same indicators on the sliders and the condenser prisms. For another reason...
But I could be wrong and there are differences in the prisms in the condenser (sorry, read your message to quickly.) Anybody able to shed light on this???? ...
I suppose Jonathan is now seriously overloaded with information. A couple of points to focus his attention: The new scopes from the bigfour (Zeiss, Leica,...
To clarify Gordon's comments, I think Kevin pointed out that optical tubelength between Leitz 160 and 170 mm lenses is (nearly) identical, indeed Leitz...
I recently acquired an unusual Leitz microscope objective which has the following engraved on its barrel; 160/0.17 NPL FLUOTAR 100/1.32 OEL PHACO2 RK All of...
