The optical microscope should be the workhorse of metallurgy in archaeology for the range of … WebA fluorescence microscope is an optical microscope that uses fluorescence to observe samples. Fluorescence microscopy illuminates a target with a specific wavelength of light, which causes the target to absorb the light and emit a longer wavelength. This causes the target to glow within an otherwise dark field of view.
