How goes your restoration? I'm curious to hear about the progress you're making! :) It went well initially, I think I have all the parts and optics in hand now, including a functioning IK condenser. Then life got in the way and I didn't have a proper space for assembly and use of the scope. However...

Congratulations on your M10! It took me years to find my first M10 so I know the feeling. You have a nice setup. It's nice to know someone who could do some custom machining to make your adapters. You mentioned that you have a "Wild/Leica filter slider unit for stereos". Do you have a part number f...

That all tracks. The reference focal length of the m3z is 100mm, so 2x is going to give you a 200mm tube lens focal length. Incidentally I have an optem 10x/0.45 HR objective which Leica rebadged for use on their macro/stereo fluorescence setups (z series macrofluo and the fluocombi, the descendant...

Is thr spacer for the objective permanently affixed? I'd be tempted to pick up a longer parfocal objective with a larger field of view like this RMS mitutoyo clone from Seiwa https://www.ebay.com/itm/175059560631 Wild stereos are essentially non-compensating so a neutrally corrected objective will ...

Update: the 1.5x achromat is not a good match. It has too short a working distance: when in focus, the compound lens front element comes extremely close to the subject! Definitely not good, and is not close to parfocal either. The best match is a standard 1x achromat which is close to parfocal. It a...

Thanks for the tips guys! Like you said, it was an easy and straight forward job. Now swapped. As I expected, Kombistereo really does not work with a 0.5x achromat stereo lens. The compound lens, which is a Leitz Plan L 25x/0.40 infinity, is "antifocal" with that, you have to scroll the focus for ag...

Well, I tried but this is as far as I could get.

The cluster of screws in this first image seems a bit daunting. I have no idea which of these could/should be unscrewed to get further without causing problems.

Hello, I would need to swap a Wild M3Z optics body from a Type S carrier (the one that provides axial option for photography) to a Wild Kombistereo carrier (the one that switches between a normal stereo objective and a Leitz compound objective). However, I can't see any apparent way how to detach th...

Hello, I am looking for the two eyepiece tubes that are screwed onto the binocular head of a Wild M5A stereo microscope. I am also looking for an objective for a Wild M5A. Maybe the objective for the previous iteration, the original Wild M5 in beige/yellow paintwork is identical with the M5A? To mak...

I'd carefully try to remove any remaining grease and wd40 residue with petroleum ether or lighter fluid before relubricating. wd40 is likely to kind of resinify after a short period. I am using synthetic watch libricants from moebius. For the rods i even switched from using grease to thin oil (Synt...

This is always a good idea. To what magnification do the stereos take you? The StereoDiscovery.V20 goes to 225x but we also have the PlanApo S 3.5x mono attachment for it, which takes mag to 525x using the 10x/23 eyepieces. Probably quite a bit of empty mag when you go that high. On the revolver, t...

Inverted scope and sample cleaning and preparation? Actually, the Olympus IMT-2 is an inverted scope. But sample cleaning and preparation is an important topic to cover. Or did you specifically mean sample preparation for use on an inverted? I would be specific for sample prep for inverted. Yes, I ...

Inverted scope and sample cleaning and preparation?

Actually, the Olympus IMT-2 is an inverted scope. But sample cleaning and preparation is an important topic to cover.

Or did you specifically mean sample preparation for use on an inverted?

So the equipment that will be available for the course consists of the following: 1 Stereos 1a) A Zeiss StereoDiscovery.V20 with Plan Apo optics, including an objective revolver with Plan Apo S 0.63x and Plan Apo S 1.5x, motorized focus & zoom, Z-stacking using Zen Blue, LED cold light (BD, DF, pola...

some HERE Thanks Tony! Those are exactly what I had in mind. Won't hurt to find more, though. I would need permission to use these of course (naturally with the owner/photographer mentioned in each shot), even at the funding proposal stage. Proposals usually aren't publicly available but I am prett...

Hi people, I've started to develop an idea for a comprehensive course on microscopy, how to use them properly, develop a practical understanding of what can be achieved using different microscopes and contrast techniques and how. Also a segment on how to prepare samples and specimens. Importantly, a...

I don’t know how similar the focus mechanisms might be, but … I have a PDF copy of the M420 service manual If you think it might be useful, send me your eMail address by personal message. MichaelG. Thanks Michael! It may be of help solving this problem. I have the repair manual for Wild M8 on pdf, ...

Yep. I think this base is optimal. The newer versions have a couple more bells and whistles but mostly they don't bring any important gain in functionality. I have one of these and will use it to set up incident light: Leica_Schott_Hi-Power_Led_spot.jpg I am in the process of getting a third-party p...

Hi people, Christmas is early this year! I was finally able to find what I have been searching for many years, the 'holy grail' of stereomicroscopes, the Wild M10! :) The scope came with the Leica ergo binocular, Wild 10x eyepieces and PlanApo 1x objective. It was on a large Leica icident light stan...

I am resurrecting this old thread because I have spent a good part of the day trying to clean the zoom mechanism of a Wild M8. The zoom knobs were turning but there was no zoom action and nothing was moving inside. It was relatively easy to open the zoom unit, though there were some problems with st...

I'll correct myself. Removing the three screws on the bottom plate actually does enable one to remove the bottom plate and the double iris system with it, allowing access inside the trinocular head. Haven't yet got the courage to attempt removing anything else. At least I now have access to the big ...

Hello, Would anyone happen to have a repair manual on the Wild trinocular head or hands-on experience of opening one up? The head in question needs some cleaning and also the slider for photo/eyepiece is very stiff. The head is like the one in the attached image. There are two screws on top but it i...

Somehow I have missed this thread :? Anyways, congrats on the Wild M10 body! May I ask how much it cost you? I am finally closing a deal on a M10 myself. It comes with the 1x PlanApo objective, ergo head, 10x Leica eyepieces and a simple Wild/Leica stand.... I will keep my fingers crossed that you ...

I don't want to day because it was pretty cheap. The apparatus is neat but I ended up taking it off in the end since it doesn't play well with tilting the head back and forth. So if you're interested I could sell it. The M10 is absolutely spectacular, night and day vs the very competent Chinese gre...

Thanks, a lot of good info there, despite much of it being bad news :( I will have to find out the particularities of the various Leitz DF condensers regarding the low end mags. It is really quite disappointing if the limit there turns out to be 25x or thereabouts. As to high end, point taken. I hav...

Ok, thanks guys for the informative comments. What about using the dedicated DF condenser that is intended for larger aperture objectives and oil immersion with those dry high aperture objectives? I would like a DF system without using oil immersion. However, I do happen to have a set of Leitz water...

Hello, Does someone know if there are any benefits to image quality or otherwise in using a dedicated darkfield condenser (i.e. condenser no. 88) as opposed to using the darkfield annulus that exists in the Orthoplan Zernike phase condenser (i.e. condenser 402a)? It lookse like no. 88 would allow ob...
