<p>
 Here are some pictures from the Optical Museum Jena, Germany, of the historical Leeuwenhoek Microscope. Please enjoy. The pictures were taken on the 200th birthday of Mr. Carl Zeiss, the founder of the microscope company Carl Zeiss Jena. Leeuwenhoek’s single lens model was the leading microscope of its time until Mr. Zeiss succeeded to reach better quality with the compound microscope made of two lenses. Today, Foldscope is bringing back Leeuwenhoek’s original design. I think, Mr. Zeiss wouldn’t mind and would be delighted to see the big user community exploring the wonders of the microcosmos. And today, ball lenses can be made with much better accuracy than in those old days.
