I know what you're thinking, "you can't just put B&L lenses on there you doofus the parfocal length will never let the objectives focus!" You'd be right, and AO lenses or LOMO lenses won't work either. Maybe Wild. I have a Wild but haven't tested it yet on here. One thing you can do, though, is notice that the stage is held aloft by four purple-anodized aluminum spacers under the stage. You can take these off, and even flip them around, shortening the stage by a whole centimeter and not even risk losing the spacers! The screws all take a 3mm hex wrench which as an American I have a pile of from IKEA furniture-- but two of the screws are longer and these should go on the top for this configuration:
It works pretty well so far, especially considering the Rayovac flashlight illuminator and that I haven't cleaned it real well yet and that this is me holding my cellphone to take the picture. I used here the trusty 10x divisible achromat from the late fifties I believe. A rabbit's tongue, prepared by our friend from the distant past, the University of Pennsylvania anatomy student:
And here is the 40x Phase, a little fuzzier than I'd like, but I didn't flip the slide over so the coverslip thickness is about 6 times the ideal.
So there you have it! An optics-less Invertoscop can be an affordable way to get some inverted microscopy in your life and to use some lenses that otherwise don't have a home. The Condenser stand came with and fits on just fine, but looks to have been ill-used in the past. I'll try to rig up some sort of condenser holder, but the light should be a cinch now that I have this LED illumination figured out.
