A solar microscope is a projection microscope that is used in a darkened room. In this case, with a space located outside the mirror sunlight on a collector lens reflected . The light bundled by the lens falls on the specimen , which is imaged onto a screen through a lens (or a lens system ). In this respect, the functionality of a solar microscope is more like a slide projector than a microscope.
Solar microscopes can be found in the catalogs of instrument makers from 1740 and were very popular, especially in the second half of the 18th century. In the middle of the 19th century they were again of scientific importance for the photography of microscopic objects.
