Bacteria in phase contrast
The four pictures on the right show different bacterial species in phase contrast.
About phase contrast
Bacteria are transparent and therefore difficult to see using regular bright-field microscopy. The bacterial cells will appear just as bright as the surounding medium and there is no color contrast. Phase contrast optics provides a solution. Phase contrast optics convert [...]
Trichinella spiralis – the “pork worm”

A tick in dark field.
The Dog Flea (Ctenocephalides canis)
The Dog Flea (Ctenocephalides canis) is an external parasite which can be found in the fur of both dogs and cats.
Papaya (Carica papaya) in Polarized Light
A piece of papaya was squeezed between the microscope slide and cover glass. The sample was observed in polarized light.
Wood of the Spruce Tree (Picea)
