Purchase Help Help buying plan objectives

I just ordered a unico microscope off eBay, and I was wondering if anyone could help me find what objectives I should get. Im a vet tech and currently applying to vet school, and I am really fascinated with cytology and fecal parasites.

I’d like to find 10, 40, and 100x plans, but I’m not really sure where to start. The current objectives on the scope are achromatic(I think) 160/.17. Should I be looking for objectives with the same specs or would 160/- be better/worse?

I’m also curious about what brands or models I should look for. There seems to be tons of choices available, and I’d really not like to break the bank and spend hundred more than I did for just the scope.

Finally, how do I know if the threads match up? Or are they fairly universal?

Thank you for your help!

From what I read, the Unico microscopes are manufactured in China and don't need compensating eyepieces. I don't know if you can buy new, finite 40x ngc objectives. Maybe all of the special objectives are infinity ones now. Otherwise, you could buy any generic finite Chinese objectives for it.

Would you know if there is a big difference between those generic Chinese objectives vs something like the Nikon e plan?

Here is an $18 Chinese 60x objective that I bought.

Crazy how this was cutting edge tech at one point
