Leeuwenhoek microscopes were small, hand-held microscopes designed and built by Dutch amateur scientist Antonie van Leeuwenhoek (1632-1723). They were about two inches long and one inch across, with a main body made of two flat metal plates riveted together and a small bi-convex lens sandwiched between them. The lens could magnify up to 250 times, depending on its quality.
To use a Leeuwenhoek microscope, a specimen was mounted on a spike and the microscope was held close to the eye. The specimen was then brought into focus on the lens by adjusting two screws. Leeuwenhoek’s microscopes were considered to be of better quality than professionally made microscopes of the time, and he used them to make many discoveries, including blood cells, sperm cells, and microscopic organisms.
