I have received my Foldscope and followed the instruction video to put it together. When I look at stuff under the Foldscope, I’m not sure how magnified it is. I put a 1mm x 1mm sample on my slide, and I could see whole in my eye… Is this normal? I thought I would be able see objects as small as 2 micrometers, but what I am looking at is a 1mm x 1mm sample, magnified yes, but still fits entirely in my vicinity.
Now there is in my Foldscope pack another lens which I don’t know what it is used for. Is it a stronger lens? Should I have put this one instead of the other?
Is there something I am not doing right? Please help me. Thank you and have a nice day
