Thanks Pete, something like that microscope is next to impossible to find here in Iran, but I fully understand your concern.

Re: Lynx Stereo Dynascope

VisionEngineering microscope are truly amazing. For soldering and repairing electronics, they offer a working experience next to nothing. They're also very expensive.

What makes them unique is you don't need to focus your eyes on the eyepieces and this prevents eye fatigue.

I forgot who it was but a member on here tried glycerol and reported that the organisms exploded. Sounds like an osmotic effect.

Re: Leitz Paperweight

Great catch. Looks like a feat of engineering. These comparison microscopes always fascinate me. I'll suggest open a new thread for the LED retrofit job, assuming precisely equal light intensity for both specimen is important (not sure about that), you need a self adapting current mirror driver.

How do you measure the exact dimensions of the prisms? Do you use a refractometer as well?

Re: My new Celestron microscope

Nice looking upgrade. Looks it has a proper condenser and that gives you lots of different illumination possibilities. Dark field, oblique, polarized and more creative ones. Happy new microscope. I love the smell of brand new stuff out of the box. Hope it smell good :D

That's jaw dropping mate. It belongs to an art gallery.

Just out of curiosity: is there any DIC compatible (and affordable) kit for cheaper Chinese microscopes? Or perhaps use Olympus universal consider and DIC inserts with a Chinese clone of Olympus CHA?

Do you know the base frequency of the PWM driver and its minimum duty cycle? That would explain the mystery a bit.
