darkfield microscopy
Side-lit specimen viewing
Darkfield microscopy is a technique that illuminates specimens against a dark background, making transparent or unstained objects visible by scattering light.
The method reveals fine details—cell edges, bacteria, crystals—that would be invisible under standard bright illumination.
Darkfield microscopy showed the spirochetes moving in the sample.
