Article is a bit breathless. > and can be viewed using a microscope capable of 1000x magnification—a technology that has been available for hundreds of years. I don't think so; maybe 100 years. To achieve 1,000x magnification with an optical microscope, you need oil (or some other fluid with a refractive index similar to that of the lens) between the objective lens and the subject. I believe the maximum theoretical m…
Are you sure? I ask because the Dutch were wild by the end of the seventeenth century, people like Antoni van Leeuwenhoek achieved 500x magnification with a single lens microscope as an example. If you wonder why I know this, it’s because this was when the first bacteria are believed to have been observed. Leading off to the next part that I’m not so sure of, but the single lens microscope was/is terrible to use, and this lead to the first compound microscopes being build shortly there after. I believe the practical limit of those is 2,500x magnification though I’m not sure when that was made possible, but many of the ones we have in education today range from 400-1000x magnification (mostly down to cost and care of the institution).
