What is the difference between compound microscope and an electron microscope? A compound microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called â¦ microscopy.
1 The conventional microscope uses visible light (400-700 nanometers) to illuminate and produce a magnified image of a sample. 2  A fluorescence microscope, on the other hand, uses a much higher intensity light source which excites a fluorescent species in a sample of interest.
