The stereo microscope is often used to study the surfaces of solid specimens or to carry out close work such as sorting, dissection, microsurgery, watch-making, small circuit board manufacture or inspection, and the like.
Antoni van Leeuwenhoek (1632-1723) is generally credited with bringing the microscope to the attention of biologists, although simple magnifying lenses were being produced in the 1500's, and the magnifying principle of water-filled glass bowls was already described by the Romans (Seneca).
