[Taxacom] Foldscope anyone?

[Vladimir Blagoderov]

It depends, of course, on the way you calculate magnification. When you
project image it may be even higher. Theoretically spherical lens can work
at diffraction limit and will resolve details of ~1/2 wave length. The
instrument is basically reincarnation of Leeuwenhoeck microscope.

Cheers,

Vlad
