I haven’t used a microscope since I was in college. I had on old school microbiology teacher that liked to torment students by whipping out an old microscope that actually used a mirror rather than a plug in light source. Thankfully, for identifying unknown microorganisms we got to use modern microscopes.
A company called Extech has unveiled a new digital mini Microsoft that looks more like a digital camera than a microscope that we would see in school today. The device has an optical zoom of 7x to 27x and includes an additional 4x digital zoom for a total of 108x magnification.
