Which of the following pairs is mismatched?
A)confocal microscope - produces a three-dimensional image
B)darkfield microscope - uses visible light
C)fluorescence microscope - uses a fluorescent light
D)scanning electron microscope - produces a three-dimensional image
E)scanning tunneling microscope - allows visualization of atoms

Accepted Answer

The fluorescence microscope actually uses ultraviolet light to excite fluorescent dyes called fluorochromes, not fluorescent light. The emitted light from the fluorochromes is what creates the image.
