Siedentopf adjustment of Binocular Head
I have an Amscope T690 microscope and the binocular head Siedentopf adjustment slips causing the tubes to go out of adjustment for my eyes. I'm wondering if there is some way to adjust the tension of the binocular head? I see some screws but do not want to mess anything up without knowing what I'm d...

Re: Cal Zeiss Jena Ergaval
Thanks again Pete. The seller raised his prices back up after the sale so I may not get one of these microscopes.
No luck either on finding the illuminator.
I live in the US, in PA.

Re: Cal Zeiss Jena Ergaval
Hey Pete, thanks for your reply! I don't own the microscope currently. Unfortunately, it doesn't come with the illuminator. The seller told me the illuminators were sold separately. That sure makes it difficult for anyone else wanting to buy the microscope. I did a general search for Ergaval illumin...

Does anyone have any experiences with the Cal Zeiss Jena Ergaval microscope?
I may be looking for the illuminator if I buy one.
Thanks,

Re: Darkfield Illumination
Thanks apochronaut for the great information about this.

Darkfield Illumination
I'm wondering if anyone has any experience with using a darkfield stop inserted into the existing condenser filter holder? How does this compare with using a dedicated darkfield condenser? Do they both achieve the same result? Advantages/disadvantages for each? You can see some discussion of this in...

Re: Private Message Stuck in Outbox
There are recent videos from his YouTube channel and one from as recent as one day ago, so I doubt that anything is wrong. I love this website and all that Oliver and everyone has contributed so if it disappeared it would be a huge loss. So much enthusiasm here!

Private Message Stuck in Outbox
I have sent a private message to someone, but it's stuck in my outbox. I have also messaged our forum administrator twice, but it never shows up in my sent items.
Can anyone help me out with this?

Re: Euromex Microscopes?
I wonder how well they honor their ten-year warranty? That is five years longer than Amscope. I had a couple of warranty issues with Amscope and they took care of me nicely. The more I read about the sourcing of microscopes today the more my head spins :-) Phil Brown: The iScope is not a cheap micro...

Euromex Microscopes?
I've been wondering about these microscopes and just how good they are? Does anyone own one? I know our leader uses them so they must be decent :-) How do they compare with Amscope and some other manufactures offering similar microscopes? I would imagine that some of them come from the same factory ...

Re: Bausch & Lomb Jug Handle Model CAH Microscope
Thanks Apochronaut for your reply.
I should have added that the plaque also shows Bausch & Lomb. Attached is a close up of this.
I wonder how much this microscope is worth? I'm not planning on selling but am just curious.

Bausch & Lomb Jug Handle Model CAH Microscope
Greetings fellow enthusiasts! Many years ago, I acquired this microscope, but I am only now getting around to wondering about its history. I see F.H. Thomas Company on the plaque but I cannot find out anything about them. I do see a lot for Arthur H. Thomas Company. Were they related? The serial num...

Re: Photomicroscope III
I picked up a PM III on Ebay back in 2017. A photo is included here. I haven't had the time to use it yet (too many microscopes!). How do I tell if mine has the much better coating technology?

Re: Zeiss Universal Fine Focusing Not Working
Let me clarify the issue. The fine focus knob rotates but the stage does not move. This can also be seen while observing. The course focusing works just fine. Both course and fine focus knob action are stiff due to the grease hardening but this should have nothing to do with the stage not moving dur...
