Sourcing non-printed parts

Lastly I’m wondering if it’s possible to use lenses from those Russian microscopes used in schools back in the 90s. Once I’ve got the basic microscope working I want to build a higher resolution one. And those ex school Russian ones are very cheap on EBay.

I guess as long as they meet the openflexure requirements in the documentation it should work (mainly the 160mm tube length, and the RMS thread). Also, I may be taking you up on that offer for a condenser lens in the future!

David,

Thanks for the useful comments. I’ll be happy to let you have some condensers when they arrive.

Regarding the objective that you chose:
I don’t understand the difference between the type A and B is it simply the exterior look ?

[WilliamW]

The specifications look to be the same, they are all plan 160/0.17. Also if you flick between the photos of the A or B 10x, the length and the shape of teh actual lens seem to be the same, it is just a different stly case.

Hi All, I recently got an email from Kozo optics who said they’re willing to ship small orders of objective lenses and quoted some pretty reasonable prices. I’ve not yet tried any of their products, but I thought it was worth sharing a link in case it’s preferable to aliexpress for anyone.

If anyone does try out their objectives, do post here so we know they’re good!
