Re: Can one adjust a condenser dovetail?
Not yet, but I will, more frequently I'll use a drop of water on there. I think I need to make a 3D printed part that holds this rigidly to replace this dovetail kludge. Having lateral play is a bit of a pain as the condenser often moves when I am adjusting it's diaphragm. I can use it right now, bu...

Re: Can one adjust a condenser dovetail?
Yowza, Pete, that's a really good idea. Funny how it didn't occur to me to print an extension to the Nikon condenser dovetail instead of trying to change my current carrier. Actually I can do one easier as a test case. I removed the dovetail from my abbe (remember, I don't use it) and what do you kn...

Re: Can one adjust a condenser dovetail?
Yeah, it is a nice condenser, and could be sold if for some reason it doesn't work out for me and I don't modify it. Maybe I should be focused on replacing the carrier with something I design and 3D print. The problem is, I'm not that great at 3D designing. I can put plenty of time into this, though...

Re: Can one adjust a condenser dovetail?
I see that you are using a .90 condenser. Did you not get an oil condenser with the DIC or is that still in transit? I don't use this abbe condenser. Just using it as a reference. I normally use my DIC or Phase contrast condensers, both if which can be oiled. I have a flip top I can use as well. Th...

Can one adjust a condenser dovetail?
My microscope does not have a aplanatic/achromatic condenser available for it. I have a Nikon NA 1.4 aplanat/achromat condenser that I would like to use. The dovetails are almost the same, but not quite. The Nikon fits almost all the way into my condenser carrier, but near the back there is a lip th...

Re: Should the condenser diaphragm work when using DIC?
I unhooked the spring from both things it was connected to and removed it. Now the diaphragm works no matter which position the condenser is in. That was easy. I don't know how many people will be in this circumstance, but now we know how to address it. I'm thinking about removing the centering scre...

Here are the naughty bits. https://i.imgur.com/rRrc2Lwl.jpg There is just one diaphragm, which is on the left piece here. The little screw goes around when you dial the diaphragm.

In this forum, Chinese manufacturers are primarily known for their inexpensive mass-market microscopes. However, they do make higher-end scopes. I bought one of these. It's a BestScope 2081.

Should the condenser diaphragm work when using DIC?
I purchased a microscope that has DIC capability and I am just getting familiar with it--I'm a beginner with DIC.

Re: Richter-Optica: Have You Vetted This Company?
I believe Richter Optica is the house brand of Microscope World. I wouldn't expect to be able to contact them separately.
EDIT: I take it back. I guess "Swift" is the house brand of Microscope World. I don't know about Richter Optica. Maybe they both are.

Re: How interchangeable are condensers?
That was just a smartass roundabout way of saying it sounds like nonsense. Where did that reference come from?

Re: How interchangeable are condensers?
Sounds like I have some fun experiments to run tonight.
Also found some more information and experiments here. That link also seems to suggest that cheap abbe type condensers tend to be infinity corrected, while the expensive aplanatic/achromatic ones tend to have a finite focus. Interesting.

The Eclipse D-CUO 1.4 DIC condenser is 2800.00. ....just the condenser. Yeah, that's a pretty good reason to do some research on fitting condensers from other manufacturers or older models! By the way, I opted for the water immersion 100X (NA=1.1), not the 1.4 fluor oil. So the difference between 1...

Re: How interchangeable are condensers?
With regards to your scope farnsy, I think the intent of the planfluor objectives was DIC, so the DIC condenser is probably a 1.4 achromat, is it not? That is my resding of it. They weren't thinking that too many customers would opt for the planfluor or planapos outdide of the DIC application. Than...

How interchangeable are condensers?
Aside from the physical compatibility (right size of dovetail), are there any other considerations when using a condenser that was made for a different microscope? For example, assuming I can make the dovetail work, is it just fine to use an achromat/aplanat 1.4 condenser made for 160mm Olympus or a...

Re: How does a collection happen?
My problem is that I'm just really terrible at getting rid of the extras. Buying microscopes is fun, and fixing them up is even funner. However, when you have microscopes that work but you don't use, the right thing to do is to sell or give them away. I'm terrible at that.
