I’m a newbe and try to build a microscope for my son. I bought these objectives but the image is a disk rather than a square and very difficult to focus.
Could someone explain how to read this reference on the photo?
- 40X means magnification factor of 40
- infinity sign means it’s plan
But what means those values on the right: “0.65” and “0.17”?
Is this objective suited for the Openflexure microscope?
Thanks for your help.
