High-resolution, upside-down microscope for oil immersion

Hi everyone

We @Marco have tried a couple of things and received some tips from @MboaLab. First we attached the illumination dovetail only with magnets, so we can easily remove it to apply the immersion oil. So far it has worked quite well and we are thinking of fixing the dovetails position with indents. Attached some pictures that show how we stuck (using super glue) small magnets on the illumination dovetail to attach it to the microscope.

The further pictures show the technique of applying immersion oil on the microscope using a scrunchy or tape to stop oil from dropping (thank you @david & @MboaLab).

Tips from @MboaLab:

  • Watch oil droplet form;
    1-Watch oil droplet form

  • Touch oil droplet to the lens;
    2-Touch oil droplet to lens

  • Oil should not drip down the lens;

  • Place sample on stage;

  • Raise lens until oil spreads across;
    6-Raise lens until oil spreads across

  • Do not add more oil before putting in the next sample;

  • After the experiment wipe oil off of the metal surface that has drip down with a lens paper and never put pressure on the lens with fingers.

I hope it helps.
