Diatom slide as imaged by the Tiedemann Drum microscope. Resolution is good but there is a significant amount of chromatic aberration, as would be expected when using simple lenses.
Micrometer scale as imaged by the microscope. Using the only existing objective the magnification is approximately 25x with a resolution of approximately 10µm.
Image of one of the samples on the slide that is part of the Tiedemann drum microscope. This appears to be the head of an insect (note the hairs).
