I build my openflexure microscope (v6) using raspberry pi camera & lens.
I wanted to upgrade for a large objective lens (high resolution) and hastily bought this one:
It seems that this one has a parfocal length of 45mm. I tried to use it - without success.
In the stl configurator I found options 40 or 50 mm. Is that mean that my objective is not feasible for that build? Is there anything I could do to make it work? (I did not use immersion oil, maybe that is also a mistake?)
Would be grateful for some answers.
