Re: Where to buy circular slide cover?

I recently bought a pack of super cheapos from China and have been pleased with the result so far, reasonably round, not seen any with scratches or other flaws yet and within thickness tolerances I'd expect (not great, but reasonable given the price)

Re: Fluke (But What Type?)

If parasitology is an interest, perhaps see if anyone you know has livestock. I do fecal egg counts and it's an excellent way to get interesting samples and to train your mind to recognize debris. I use McMaster slides as they make counts easier, but they are not absolutely required.

Re: Can the same videography quality be achieved from a binocular head compared to a trinocular head?

In most trinocular heads there's a prism or the like that diverts the light path through the camera port rather than to the eyepieces, in such a setup you get the full intensity of the light to the camera. With a bino head you will typically get a 50/50 split of the available light so the camera wil...

Someone correct me if I'm wrong, but a short focal length planoconvex lens like you would see for an aux lens mounted at the bottom of the condenser (plano toward condenser, convex toward light source) should correct that, yes?
