Microscope

[|Optical lenses], 13th century - Refracting light through glass is one of those simple ideas that took a mysteriously long time to catch on. “The Romans had a glass industry, and there’s even a passage in Seneca about the optical effects of a glass bowl of water,” says Mokyr. But it was centuries before the invention of eyeglasses dramatically raised the collective human IQ, and eventually led to the creation of the microscope and the telescope.

[|Microscope] - an instrument used to see objects that are too small for the naked eye.

There are many types of microscopes,
 * [|optical] or light microscope - the most common and first to be invented, uses light to image the sample
 * electron microscope (both the transmission electron microscope and the scanning electron microscope)
 * various types of scanning probe microscope

Fluorescence microscopy, where scientists shine a particular kind of light at whatever they’re trying to illuminate and then that substance identifies itself by shining a different color or light back.
