For free in DFW: Nikon Eclipse E400 and E600 bodies
I moved to a smaller place and need to downsize, so I am giving away these two microscope bodies that were a project I never got around to. http://i.imgur.com/w18mWKtl.jpg http://i.imgur.com/1y3LaA9l.jpg Included is one binocular head in good condition and a riser. At least one condenser (not shown)...

Re: One of the best microscopy-related investments I made
I have a box fan and a 20x20 furnace filter (high MERV) set up next to my microscopes for that purpose. Put the filter on the intake side of the fan and it sucks to it so all air that goes through the fan will go through the filter first. The contraption is crazy cheap (and replacement filters and c...

Why isn't phase and darkfield done in the back focal plane of the objective?
I was rewatching Peter Evennett's delightful lecture in which he does Abbe's experiments ( https://www.youtube.com/watch?v=60_jgZtyR6U ). When he discusses darkfield at 51:41, instead of using a patch stop in the condenser, he uses little film with a tiny dot in the back focal plane of the objective...

I'm glad this scope is working out for you, Vish! You seemed to have no trouble finding a matching dovetail.

Yes, the optics are compatible with Olympus' infinity system. Eyepieces should be standard size. I don't know about the condensers and sliders.

Re: Viewing Bacteria With Bright-field Microscopy
Would DIC be any more useful in seeing detail? It depends on why you can't see the detail. DIC, phase contrast, darkfield, and oblique illumination allow you to see things that you couldn't see otherwise because they are **transparent** when there is a super bright light behind them. We can think o...

Re: Anyone purchased or used the Motic Panthera C2 Microscope?
I would question how much better the C2 is than something like an AmScope T720 with a quintuple head. Differences would be small unless you get the fluorite objectives.

Re: Agonizing over a BX60
Sounds like a solid deal to me. Also, almost all generic infinity-corrected objectives from China are compatible with the Olympus system. Shouldn't be hard to find a good 100x for under the budget you suggest. Aliexpress is lousy with them, as I'm sure ebay is as well.

I talked with the salesperson again and explained a little more what I was wanting. After a couple of days she came back and said that the maximum field number is 30.7mm.

Re: BestScope BS3090 Stereo Zoom Microscope (Nikon SMZ18 clone)
I asked the salesperson and they said the field number is 23, but I think they were just looking at the eyepiece field number. You are referring to the maximum the scope itself could handle, right? I'm sorry I don't have better information.

Quick overview of my BestScope BS3090 stereo microscope. Also known as the "NSZ818." This is a close imitation of the Nikon SMZ18 microscope, from what I can tell. The aesthetics are a little different than is pictured on the website, but the performance is what you would expect from a modern CMO zo...

But I think calcium chloride is much safer than silica gel in this respect. From what I've read, calcium chloride can absorb much larger amounts of water and holds on to it, while silica gel absorbs much less and its action degrades rapidly as it accumulates water and there's a much greater danger ...

Holy cow, what a great event! Way to be patient and really capture something cool.
I mean, that kind of thing must happen all the time given the number of rotifers around, but I've never seen it, much less captured it on video.

Re: LW Scientific "Innovation" vs Amscope "T720" - Any Difference?
Maybe it's just me but I'd definitely go for the quintuple version. In my opinion, there's a lot of usability difference between 4 and 5 objectives. Love that 20X magnification (or 60X, if you prefer)!
