Diatoms from a prepared slide of historical material

[gekko]

The first image of the slide itself has the information. The images that follow are of areas from the slide.

Thank you for looking.

Thank you very much for your kind comment. For darkfield, I use the DF position on my phase-contrast condenser which works for the 4x,10x, and 40x objectives.
