Re: Epistar microscopes
Halogen bulbs should still be cheap if sourced right but LED replacements are doable. I use a CREE x-pl led in my epi illuminator and it's worked great for me. But it will take some careful DIYing, there aren't great drop in replacements.

Oddly I think Nikon (?) used a similar cable plus which is what I was thinking of.

Re: Olympus S plan vs S plan APO for DIC
If you are serious about wanting DIC it's important to be flexible. Rather than building a particular system and hoping you find the right DIC set you will probably have a lot more luck (and probably spend a lot less) casting a wider net and finding a dic system, any dic system, to build the rest ar...

Re: OM1 Objective adapter
Are you looking to just put an objective directly on your camera? There isn't a single adapter, you need variable spacers or a bellows to go between your camera and the objective. These are modular bits and fairly inexpensive. For aps-c I would use m42 spacers and helicoids, but it may cause issues ...

It depends if you have a normal illuminated base or a brightfield/darkfield base. Darkfield won't work with a frosted plate.

E is for educational or economical. They're the budget model either way, smaller field of view and probably worse color correcrion. I am not familiar with cfwa eyepieces though. The CFW and CFWNs are the higher end options, and they did have one rarer type with premium cllor correction. Personally I...

Re: [Beginner] Photography with Nikon SMZ-U
When you say you can't get the sensor in the right spot, you mean to be parfocal with the eyepieces correct? Because as you mentioned, it positions the sensor too "far away" to be parfocal. Yes, exactly. And of course if you just refocus to move the image circle knto the sensor you theoretically ar...

Re: [Beginner] Photography with Nikon SMZ-U
It comes down to two things: how big the image circle is and where it's positioned. By default the smz-u puts out an image that's a bit over 27mm in diameter, which is actually larger than it was specced for. If you put an aps-c sensor with a ~27mm diagonal right on the image you get a nice image th...

Re: Good Stereo Microscope?
The Nikon standard photography setup does make it annoying to use a dslr via direct projection since the flange focal distance is just a bit too long. There are workarounds but nothing beats buying two cheap mechanical adapters and just having it work.

Re: [Beginner] Photography with Nikon SMZ-U
How much do you want to spend? One easy solution is to get an aps-c mirrorless camera and directly adapt it to the photo port with no intermediate optics.

Re: A microscope for Christmas….
Apart from the question of how much money spent, I think the most relevant question is what it is going to be used for. Absolutely. If there's no strong direction a stereo is a good general purpose scope that's easy to use and practical (splinter removal). But it's not good for hunting tardigrades.

Re: Working in an "universal condenser" for Nikon Optiphot
That is fascinating. As you say I don't know if it's bad news for the dic or if it's good news for the oblique. Probably the latter, you're getting really good lighting. Probably time to try it on some diatoms or other classic fun subjects.

Re: SMZ-10 OPTICAL AXIS COLLIMATOR
The problem is usually in the head, not the zoom body, even if nothing is loose. Not 100% of the time but usually. You'd need to mix and match with known good components to isolate the issue. It's never an easy fix, usually not really possible without factory tools unfortunately.

Re: Good Stereo Microscope?
Yeah, it's a lot of scope for the money. You can also keep an eye out for Olympus SZH-10s which have similar specs, maybe not quite as good with the default df plan 1x objective but with the bonus of sometimes having a dual-objective revolver to extend the magnification range.

Re: Good Stereo Microscope?
Yes, the 508's 8:1 is going to feel very similar to the 10:1 on the smz-u. The 508 is rated apochromatic but not planar. The 0.075 numerical aperture of the 508 is lower than the ~0.1 of the smz-u ed plan 1x so it will resolve less and be less bright, though color correction may be better on the 508...
