A diatom mounted directly on a sand grain which, in turn, is mounted on the end of a 1mm optical fibre. The *only* light in the scene was transmitted up through the sand grain via the fibre (with a Schott halogen light source shining down the other end).
200 shot DMap stack, 50x Mitty on 135mm tube lens for 33x onto FF running in APS-C crop mode. FoV is <0.4mm wide.

Very very nice image!. A pleasure to see you resuming your work with diatoms
Did you place any liquid or solid media for light transmission between fiber-sand grain-diatom?
I can't imagine how to do it.A diatom mounted directly on a sand grain which, in turn, is mounted on the end of a 1mm optical fibre...
