I think there are a lot of scientists who feel nature and research is more interesting than the company of other people. I say company, as what people do or what they feel and think may still be interesting as such. I would call this state of personality introvertism. I share myself your feelings an...

Thanks. Maybe so. The adapter is rather heavy, robust and made of steel, which gives me the impression it is intended to be used directly and not on top of the tower (red part). While the lower phototube I have is very light and made of aluminium...

Thanks. I know and I have also the phototube which fits into the trinocular head and the eyepiece can be fitted inside the tube. I have no upper parts yet, however planning to make. What I mean is that the adapter has c-mount thread and a digicamera can be inserted directly. I assume this is how it ...

This camera adapter came with my Leitz Orthoplan. It has no lens inside at all or any place for attaching an eyepiece. If the Orthoplan system needs a projection lens/phototube with an eyepiece for proper image correction - as far as I have understood right - why this adapter has been manufactured i...

And one more question:

6. + inside a circle (also white, engraved)

What does mean in Olympus eyepiece the following?

1. P = polarization or plan?
2. micro = for microscope???
3. FK = photo compensation?
4. Bi = for binocular head??
5. a white engraved square, on the left when 10x magnification mark is down

What is not always understood is that a compound microscope itself is only a part of the job. The other part includes more or less complicated sample preparation which often needs special knowledge and especially patience. When I was a child and got a cheap microscope as a christmas present, there w...

I don't know about Citoval, but how about this one https://www.ebay.com/itm/VTG-Soviet-Era-LOMO-Binocular-Stereo-Microscope-USSR-MBC-MBS-1/124247339534?hash=item1cedb7f20e:g:ojUAAOSw3JhfAKfV I have a one just like this and I am quite satisfied. Is it possible for you to go and see. It is in Kiev, ri...

Thank you and Merry Christmas and Better New Year for all. Thank you all for valuable contribution here!

Not that I didn't want to add my wishes here, but maybe I was too shy to do that. But now it is done. Would this be a reason for the volume?

Thank you so much for valuable information. I saved all these instruction for future and hope I would never need it.

What is the construction of a collimator? Is it possible to build it at home? Could e.g. a laser pointer used for this purpose?

Almost done: focusing mechanism, stage, objective turret, everything has been disassembled, cleaned and relubricated. Only the ocular head is waiting for service. The job has been quite easy and straightforward and I really enjoy working with all those fine little parts which has been very well made...

In the orthoplan (which is indeen 170mm) both 160mm and 170mm objectives work well, athought some of the parfocality is lost. So changing objectives you need to refocus more. I don't know about the phototube but I think you will find out when you try. I have also another trinocular head, which is bl...

The coarse focusing feels a bit tight - but not knowing how it should feel it is difficult to judge if something needs to be done or not. Hard to know what you mean by tight. But trying to get something to compare with: When I hold the coarse focus knob between my thumb and forefinger, it is rather...

You are welcome! I have not been able to locate a manufacture year. See the list of Leitz serial numbers and years here: https://sites.chem.utoronto.ca/chemistry/jbj_archive/Optical%20Equipment/Chemistry%20Library/Leitz%20Microscope%20Serial%20Numbers.pdf You will find the serial number on the top o...

Thank you so much! Your help is highly appreciated. This indeed explains the existence of the two stoppers: I was wondering what are they for.

It will take some time and effort to take off the remains of the broken fixing screw and clean the threads

Thank you so much for your kind response and photos! I started the dismantling and cleaning. Whant I found is that Olympus grease tend to form some very hard stuff (polymerize?) rather than just getting more stiff. The objective stage appears to be rotatable - at least to some extent - and this is c...

I am not absolutely sure if this was a rational purchase… Anyway, Olympus FH is the most cute microscope I have ever seen. So when I saw it in Ebay, I just didn’t have any other choice. My offer 150USD was accepted, however the shipping from US to Finland doubled the costs. And, what is more, almost...

interference filters (and the mirror of course) do have a limited shelf life even if securely wrapped and tucked away in the depth of a drawer. Several years, not decades. I am curious: what is the physical nature of the process of deterioration? What is the structure and composition of the mirror ...

What is this item for? It is like variotube, however lacking the magnification changer knob. The tube in the center is plugged, and it doesn't look like phototube.

The Rising cam offers 20 MP and is the best dedicated camera I have tested so far - its available on Ebay for about $800. Could you further specify the model of the best camera as there seem to bee several different models of Rising cam? I have also the problem of selecting a fluorescence/multi pur...

Here is a beautiful CTS Universal. Love the , probably Mahogany , armrests.

This is something... Really very elegant!
I would very much like to replace the plastic hand rests of my Orthoplan with wooden lacquered hands rests like this.

I have extremely limited experience with Olympus microscopes and never used your model. However, would this be of some help?

In what board should I ask my question: "My microscope"? "Beginner’s corner"? or "Microscopes and optics"?

I would select "Microscopes and optics"

Welcome!
You will be loved here. Great community, great people. A huge amount of real professional microscopists and useful information.

I don't have a filter tray in my Orthoplan condenser. I think normally there is no filter tray in Onrthoplan condensers. The Ebay link represents Bereck condenser which, as far as I understand, is for a microscope without a built-in Köhler illumination, perhaps for an older model of Ortholux. I don'...

I checked this morning: Actually the difference in focus between 100x oil objectives of 160 and 170 is very small. So you shouldn't smash anything.

To question 1: I have used both in Orthoplan with no problems. In priciple, you are right with the parfoaclity. The most difficult objective to focus is 100x oil immersion. So it is most convenient if you have that objective and the one with the second highest magnification (e.g. 40x) of the same tu...

Photos of the microscope? Why? There are some here:

Have you posted photos of it anywhere? Absolutely not. This won't happen for a long time. First of all, I must buy a better camera to take any pictures which could be published. The second problem is that my led lighting is not powerful enough for phaco so I have to build a better system for that. ...
