Thanks for the replies and the mirror is glued in place. Now what is the process to align the mirror and how accurate must it be?

Thanks,
henryr

Since the mirror is so light I'm thinking one small drop of slow drying super glue should hold it in place. And, with the mirror anchored at only one small spot, wouldn't the effect of differential of thermal expansion be insignificant? My only concern is aligning the assembly using the three screws...

Thanks for the info. And I appreciate your point on expansion differential. That is an important consideration. And the 1031 illuminator lights up when the cable with the grounded plug is plugged in. So what does the small round plug under the base do?

Thanks,

Hi all, I just received an American Optical XH10TU-LW. It is in great condition except for one problem. While unpacking it I heard a rattling sound and found that a mirror, that should be mounted on a 45 deg. bracket, was lose. My question is should I re-glue it to the bracket with super glue or som...

After reading so many positive posts about AO infinity scopes I'm thinking of parting with my Leitz SM-M and Dialux. Would AO infinity objectives provide improved viewing?

Thanks,
henryr?

Thanks. And if I finally understand correctly what you have described, I can't think of a reason why I would buy a BF scope if buying a PC scope and several BF objectives gives me the capabilities of PC and BF.

Thanks again. But to make sure I understand, you wrote diaphragms. Is diaphragms an alternate term for objectives?

Thanks,
henryr

Thanks for the detailed reply. So my amature interpretation is that BF specimens can be viewed on a phase system but their could be some spherical aberration, and that could be corrected by using BF objectives. Is that correct?

Thanks,
henryr

After reading posts in "Do we need Phase Contrast" I read that some types of specimens can't be seen, well or at all, with a bright field microscope which leads me to the following question. Will bright field prepared specimens be viewable on a phase contrast microscope with its phase contrast conde...

Thanks for the info. I'm going to check jones springs.

Thanks for the reply. Over the years Leitz made some with the leaf spring and some with two compression springs. I need one compression spring. I'm in Newington, Ct.. Please don't make one. FYI the dims. are: WD .02, OD .094, FL .305

I disassembled a 600 series condenser about two years ago and, thanks to help from members of this site, I am now ready to reassemble it. But it appears that, sometime over the last two years, I misplaced/lost one of the two small compression springs that allow control of positioning of the condense...

Thanks for an in-depth description of various causes of dirty looking images. I enjoy your very enlightening and interesting posts.

That I was told, buy the seller, that the photo is looking through the eyepieces with the light on.

I'm very close to buying a series 10 but some have a less than clean image when looking through the eyepieces. And some have no cover over the vertical tube or the binoc tubes so could stuff have fallen on the prisms? So is it an easy or difficult task to clean the prisms? Here is an example of what...

It appears that, sometime over the last two years, I misplaced/lost one of the two small compression springs that allow control of positioning of the condenser lens via the two knobs at the bottom of the condenser. Would anyone have a spare spring that they could part with? I would gladly pay for it...

The reason I ask is that I found a great looking sixty with a graduated stage and a few series 10 and 110 without a graduated stage. The sixty is only $30 so I would buy it just for the stage if it would mount on the a 10 or 110.

Thanks,
henryr

Thanks Apochronaut for the info. So I'll keep the Leitz and Zeiss stuff with my Leitz SM-M and Dialux. Now that brings me to another question I've wondered about. I'm really a neophyte when it comes to microscopes, but in the late 60s I worked in a metrology lab at the leading jet engine maker and c...

Can the stage from a AO sixty be mounted on a AO 1036 or AO 110?

Thanks,
henryr

Thanks for the info. I'm looking for an inexpensive scope for my 10 yr old my grandson and wanted one that could work with a camera and have a moveable stage. Now I don't know the quality of older AO eyepieces and objectives so I thought replacing them, with excellent condition Leitz and Zeiss spare...

It seems that an AO sixty I'm considering may have a similar problem so all the responses and diagrams with parts list make me think I can fix it. However this scope is a bit different from all the other series sixty I've seen. The head has a second vertical viewing tube, maybe for a camera, and it ...

I thank very much you for the reply. My scopes are a leitz dialux and old black laborlux so I'm used to pretty good optics. Now I'm looking for a microscope for my 10 year old grandson and I don't want to get a kids scope. So after much searching I found a LOMO in very good cosmetic condition on eba...

Hi all,

Does anyone know what the mounting diameter of a condenser for this scope should be?

Thanks,
henryr

Thanks for the info. I recently noticed that my 600 condenser has a bottom lens marked Kond. 600
LABORLUX. Could this be a K4 lower lens mentioned in a few posts?

Thanks,
henryr

Maybe you can help with this question. My condenser has two small wound springs to apply force against the brass flange of the lens barrel. Then I found this photo of another 600 condenser that uses a flat spring for the same purpose. The last pic is my 600 and you can just make out the springs to t...

Here are a few pics showing the area and parts that I'm thinking should be lubed? I thought the top and bottom surfaces of the brass flange and the two centering components that are moved by the centering screws.

Thanks for the reply. From my days working on old compur shutters the first thing I learned was never lube iris leaves.
My question is on the area where the lens barrel flange rests on the bottom of the bathtub where there are two finger screws used to adjust the lens axis.

So now I'm ready to reassemble the Leitz 600 condenser and I have a question about lubrication. The only place that I think needs lubrication are the parts that slide against each other when the two fine positioning screws, at the bottom of the bathtub, are used to move the condenser lens axis. And,...

Thanks for all the info but maybe I didn't approach this task properly. My difficulty was working with the leaves at the bottom of an approx. 1" deep well. Now I'm thinking that I missed the obvious which would have been to unscrew the section/sections that the 22mm lens is mounted in. If that were ...

I thank you and Charles for the info. I took my 600 apart about two years ago and it took me almost that long to get the iris leaves back in. Over the time I struggled to get them back in it became an obsessive compulsion and after a number of iterations of making help tools on my lathe the iris now...
