Description: Made by me in my Pennsylvania USA craft shop/lab. All Sterling silver except the lens, which I made/ground/polished from a shard of a broken window pane. The threads were swaged with my hand made taps and dies. Typical magnification power is 100-150 X. Made with primitive tools and techniques just as Leeuwenhoek would have made his. Most of Leeuwenhoek's microscopes were silver, but the silver ones were scrapped for the silver value soon after his death. Most of the surviving originals are brass. Silver reproductions like this one are very rare. The photo of the "specimen pin" is taken with an iPhone held up to the lens as you would position your eye. The distance from the lens to the pin is a little less than a tenth of an inch. This means the magnification of this microscope is a little more than 100 X.The calculation is: 10" / focal length = magnification. In this case 10" / 1/10" = 100 X. Generally, the lens has to have a magnification of around 100X, or the specimen pin could not be in focus. For example, a cheap reproduction of a Leeuwenhoek microscope with a lens of 10 X would focus an inch away from the lens, and nowhere near the specimen pin, which is about 1/10 inch away from the lens. A 10 X lens cannot work in this kind of microscope. This microscope functions just as Leeuwenhoek's single lens microscopes function. It is a working reproduction.
