Although crude compound microscopes had existed since 1995, Hooke imroved the optics and invented several of the helpful features found in microscopes today-a stage to hold the specimen, an illuminator, and couarse and fine focus controls. His microscopes magnified on about 30 times, but with them he was the first to see and name cells.
