Coating the lens is the final step in our manufacturing process. An antireflective coating maximizes the energy of light transmitted through the lens. For example, the transmission for two uncoated surfaces of glass (single element) is about 90% (for Nd = 1.5). When the two air-to-glass surfaces are single-layer coated, the transmission ...

The tiny cap containing the material, the grinding sand or the polishing paste, fits over the glass. Leeuwenhoek used a spring-pole lathe to make the screws for his microscopes as well as the lenses. Foot power with a spring pole gently turns the cap around the glass. Leeuwenhoek's pole was so big that he had to cut a hole in the wall.
