Leitz Dialux Pol

#1 Post by Charles » Thu Mar 17, 2016 11:52 pm

One of my favorite scopes are the Black Leitz...especially the Pol versions. Here is my latest buy, a Leitz Dialux Pol trinocular with 5 objective centering turret, rotating stage, rotating polarizer and rotating analyzer with a rot 1 wave plate, all in excellent condition.

hi, i'm in the process of fixing one of these up, it's a petrographic version w/ circular rotary stage (like the one pictured in the above posts) which i can't figure out how to get centered. does it have a stage-centering feature, or is centering only available via the objectives? from what i can tell so far it is quite a nice microscope. from serial number it is ca. 1969 or '70.

The Leitz circular stage is not centerable. I think most pol/petrographic microscopes do not have centering stages because you would be constantly centering the stage for each objective. So centering the objective is easier than centering the stage since each objective would only need to be centered once. You have two ways to center the objective, through the objectives themselves or the turret or objective holder. Zeiss pol objectives have two centering rings built into the objective and turning the rings move the objective lens group to center them. Others have the capability to center the objective through the objective turret where each objective opening can be centered independently by two screws which move each opening in the x-y direction. The Dialux above has the centerable objective turret.

Very nice scope, Charles! Black Leitz scopes are classics! Sometimes I wish Zeiss stayed with black enamel for longer. Black paint makes allot of sense in microscopes. It shows dust and oil very well.
Dialuxes date all the way back to the late 30's and were the first truly universal research microscopes.

Thank you!

I like the 'Black' era in all the scope manufacturers scopes. A lot of good looking microscopes came out during that time period. Zeiss did have the Junior, GFL and WL in black during that time period and I think all the manufacturers moved to grey scopes about the same time.

There are three versions of the Leitz Dialux. The first version had a 'T' base like the Ortholux. The second version has the 'V' base and the third version came out in the 'Grey' boxy looking scopes.

I know about black WL and GFL (I think GFL only came in black) I have a stand as well, and I'm in the process of assembling full trinocular black WL POL/DIC scope with all period-correct components. Letiz actually stayed with black longer then Zeiss. Well into the 70's. I sometimes toy with an idea of taking a spare Universal stand I have and after component disassembly sand-blast the stand and base and then take it to a custom auto shop so they can paint it with gloss automotive enamel. I already have black tube and tube head from Ultraphot I, so the rest should be easy.

The closest Zeiss had to a black Universal/PM was the PMI and their first Universal. They are a machine grey with black accessories. I have a few black GFLs, WLs and Juniors as well.

And here is a pair of WLs with DIC. The black has the old DIC system with single arrow condenser and single beam DIC slide. The white has the newer DIC system with individual DIC slides for each objective.

Well, Charles, I have no where near your collection! It is very impressive!
All I have is couple of Universals (one very nicely equipped and one basic), a WL, 2 ICM-405s, few stereos and some miscellaneous stuff.

Thanks. These are my main working scopes. The reason why there are two heads on Universal is not because I have 4 eyes, but so that my kid can look through at the same time and I can explain what we are looking at. This universal was practially brand new when I got it. Not a scratch anywhere and I still have the original fitted cases for it. Some parts were still wrapped in packing paper. At some point very reach university got it and never ended up even setting it up. It just sat on the shelf for almost 40 years and then sold for pennies on the dollar. The original invoice states almost $20,000 in the early 70's. And the scope was in pretty basic configuration. 5 plans, aplanatic 1.4 phase condenser phototube and old style round 50W light. I ended up buying IIIC epiilluminator, IIIRS epiilluminator, sets of filters, DIC (single arrow) equipment, sets of high end objectives, septiple turret and additional 100W light as well as HBO light.
